Update: Now after 700 miles  06 6.0 Power Stroke
930445
well I read all the hype about this product. I really was not expecting much from it. But I thought it was worth a shot for my Ford 06 6.0 Power Stroke with 90k.  Now after 300 miles I can actually tell a difference in start up and even a little better power improvement. It actually does sound a bit quitter when running. Overall I was pleasantly surprised by what it has done at this point. It really does seem to help, especially at startup.  Update:  Now almost 700 miles there is a significant positive difference. It starts up much easier, runs quitter and smoother especially inside the truck. I have yet to check MPG to see if there is any improvement, if there is great. If not I will still be adding this to my next oil change on the simple fact of how it starts. I have experienced zero negative issues since I added this other then to my wallet!

I'm boosting 3psi over factory ECU setting and have used RP since I bought the car, changing at factory recommendation. This engine is known to gum up the oil and starve the turbo but I haven't had any probs at all at 110k miles.

Off to a rough start but it all went well. My experience with V&H Fuelpak on 2013 Iron 883

I had this weird problem and was about to post a fix video on youtube but didn't get time :) Whenever I ran Autotune, it was like in Ghost mode! The throttle just went off on its own and it was COMPLETELY unsafe. I contacted V&H and were with them for many hours trying to figure out the problem... They recommended starting fresh, or flashing back the stock.. but none of it worked (this was the day before) and they were closed for the holidays after.
After several hours of trouble shooting on the next morning... I finally figured it out! Mine was somehow related to a faulty Jiffy stand sensor... and thanks to FP3 app and its ample helpful options.. there was an option in the app to turn this darn sensor off! Click on View Edit Maps > Select your map > System Switches > Jiffy Stand > Turn that darn thing off!!! Autotune went fine after this and I was able to ride smoothly with it left on.

Make sure to flash your findings before you turn off your bike for the night. Mine did not start the next day because of the "Engine too cold" error. I flashed the autotune values and it started up fine.

All in all, once you get it to work right, the bike runs like a well oiled smooth and powerful machine!

Its been a couple weeks and so far so good. Factory sensor went bad at 110 k miles. Obviously if the check engine light were to come back on, my review would be much different. Time will tell

Generally good vehicle, but I've had my share of problems in the 71,000 miles or so I've had the car, which I purchased new.  I had to replace both driver side front and passenger side front window motors during warranty period, so bought extended warranty - which turns out to be good because I later had to replace the same for both rear doors and again for one of the front doors.

I also scraped the front fender against a post (barely visible scratch) which caused one of the fender clips to break, which Toyota refused to replace under warranty.  Not really a problem, since all other clips are intact, but I've now noticed several other Toyotas with similar fender issues, indicating to me that this is probably a design flaw.

Finally, over the past several months, I've noticed fuel economy has dropped significantly.  Originally I averaged over 40 mpg combined, and got about 525 to 575 miles per tank, sometimes as much as 600 miles in a tank.  My last tank averaged 36 mpg, and I'm now getting about 450 to 525 miles per tank, so it's become somewhat more expensive to drive.  My commute schedule hasn't changed.  Dealer says nothing wrong, or I'd get a warning light or computer code ... but I disagree.  I think that either the hybrid battery isn't maintaining a charge as well, causing the gasoline motor to engage more frequently, or I've got a small gas leak somewhere that is as yet undetected.

Having said that, it's comfortable, plenty of power, easy to drive and it's far from being a lemon, so not considering (yet) trading it in on a new vehicle, but I probably also wouldn't buy it again.

Replaced all 6 in car along with the wires (http://smile.amazon.com/gp/product/B0055B0AZ4/ref=cm_cr_ryp_prd_ttl_sol_7) and since then the drive is amazing. I had a misfire in cylindar 1 so I decided to do a complete maintenance afterwards the stuttering once i pushed it over 40mph was gone. Also gain a bit of gas efficiency, about 2 extra miles per gallon. Startup is back to near new as well. Will buy every time as long as i one this car

Update: Installed easily and working great now 100,000 km later!  Smooth as silk still would buy again when needed!

sounds a little beefier than stock! 06 Jeep Grand Cherokee. After this, new Cat, and tail pipe I get 1 mpg more than I did with stock.

Installed on a 1986 460 in a class C RV with 26K original miles.  RV had to be floored to climb a 7% grade at 40 mph.  I installed the timing chain with the crank in the 4 degrees advanced keyway and the initial timing at 12 degrees advanced.  My spark knock/dieseling when I turn the key off after the engine warms up went away.  Seafoam made it a lot better but the timing chain made it stop all together.  I can climb those same hills and hold 65 mph at 3/4 throttle.  Also, I have a factory electric fuel pump and I was able to reuse my 2 piece fuel pump eccentric.  I used the fel-pro timing cover/water pump gasket & seal kit with The Great Stuff and it is still sealed over 1,000 miles later.  Don't forget to put assembly lube on the fuel pump eccentric if you have a mechanical pump to prevent a damaging from a dry start & torque everything to Ford recommendations and you should be good.

Got it for my '02 Protege5 at around 150,000 miles. I don't think the old one was worn out yet. Changed it for preventative maintenance. Anyways, had my mech put it in for 'round $500. You're gonna want to machine the flywheel and change fluids. Pedal felt VERY light and engaged close to the floor for the first week of breaking in. Barely had to tap it to shift. But it's back to the stock feel now; engages in the middle with some weight to it. Same amount of travel. Had it for almost a year now without any problems. Treat this car well and it will last many miles.

Worked great in my F22A6. It's a 24 Hours of Lemons CB7 race car and I have 1 race on them so far, they're holding up great.  I just did a quick ring job with the block in the car and a dingleball cylinder hone. Stock 250k mile pistons.

Broke them in hard immediately after getting the motor back together. 10 full throttle runs from 30-60mph in 3rd letting the car engine brake back down to 30 each time with the throttle closed.

These plus spark plugs, fuel filter, air filter, cam location sensors and ALL drive line fluids changed and greased along with all engine fluids changed on a 5.4 Tritan with 204K well maintained miles on it my fuel mileage has almost doubled.  For a 4 wheel drive 44 gallon fuel tank ford excursion that is quite impressive. Was getting around 500 miles on around 38 gallons of gas and just turned up over 800 miles since last fill up and fuel light hasn't come on yet! Power gain is incredible. Put it to the floor merging onto an interstate not paying attention to speed and had to brake at the end of ramp cause when I looked speed was 80 mph and had not hit overdrive gear yet at 3700 rpm.

Have put about 250 miles on them, and so far they are great.  Will update once I get some real miles on them.

Update 3/16: Cleaning up my bike today and found a bulge and tear in the sidewall of the tire.  Guess I should have listed to my LBS that said he replaces a lot of these due to sidewall tears.

157,000 original miles. This is the first time it has been drained and filled. Symptoms: shifting was choppy, stiff, and difficult. I thought maybe clutch or MC/Slave going bad. After, drain and fill, shifting is noticeably smoother. Almost like when it was new. Fun to drive again. I am very happy. Thanks Redline tech support.

CDI box failed, but that was due to electrical bugs in my scooters system wiring.
It's all sorted now and the Orange Coil Wire is still going strong.
(one thing though, do yourself a real favor and buy a proper NGK spark plug #C7HSA, or Iridium CR7HIX, your bike will thank you)

If you have the tools you need (8mm and 10mm sockets, ratchet with extension, 9/16 wrench, pliers and scissors/sheers), you are good to go. It took me about an hour between locating tools, reading directions and installation. If I had to do it again, should take 20-30 minutes now.

The sound it makes now is awesome. See the before and after video I attached.

The only issue I have is that I do not see a big 17bhp advertised gain in horsepower. But there surely is some. My 2012 Durango used to do 0-60 in 7.2 seconds when it had under 20k miles on it. I have a YouTube video of that. Now that it has about 70k miles, it was doing about 8.2 seconds. After I installed the intake, I see about 7.7 seconds. So, I recovered about half of the lost horsepower I had lost. I am happy enough with that. The best part is the sound it now makes and the RPM goes up much faster. Maybe a tune up will help. I also see some gain at higher speeds, but I don't have a quarter mile run numbers from my OEM intake.
See Before/After pictures and video.

Its a good outline for performance upgrade. I am hoping just for 50 hp gain. You will still have to figure out the details to make it work.
