So can anyone tell a difference with the claim of maintained maximum horsepower of 25% longer? Do you feel more power compared to other synthetic use like Mobil 1, Pennzoil etc.? Or is this more of a marketing ploy? Thanks alot! So can anyone tell a difference with the claim of maintained maximum horsepower of 25% longer?

I can't feel the difference, I just know that when I change my oil, it is a lot cleaner than other brands at the same interval.

Im not sure to be honest i do know i get more distance between changes stays cleaner longer

I've picked one up myself, based on all the favorable comments and reviews here-I like the selection of the range of speeds allowing it to run down at an idle of under 4 watts, and 90W on turbo mode. Good to hear it determines the replacement indicator based on the airflow restriction rather just on run time.

I would have to honestly say that I don't know, what I do know is that I do feel and hear the difference, I plan on changing out my exhaust later on down the line which, from what I've researched is where you would see a more sizable increase in horsepower/fuel efficiency, but I know someone with the K&N; setup who wishes he would've known about Spectre because you really can't tell the difference in quality and performance, and I'm sure you've the price difference. I would highly recommend.

There are four settings. 1. Towing setting gives you an extra 40 HP. Noticeable but barely. 2. Race. This gives 80 extra HP also quite noticeable. 3. Extreme. This gives the full 100 extra horses and is where I keep it all the time. I get better mileage than I did before (10% or so) and it makes the best performance. 4. Custom. This is where you manually select the fuel and timing. You can either make it super sweet or FUBAR. I have not messed with this.

I have only seen slight improvement not mpg, maybe 3-4 mpg more. The big improvement comes from horse power and torque.

You can definitely feel the shifts are quicker and firmer. The biggest difference by far is the extra 100 HP and torque. It absolutely is the best mod I did for my 02 F350. Gas mileage went up about 5% too. Not much but when it turns your truck from docile behemoth to a sports truck AND gives better mileage it is a win win.

Better than North American synthetic blends? I don't know. I purchased it because it is factory fill for Porsche & Ferrari and I drive a Porsche Boxster. I paid more than you. If you can get it cheaper than other synthetics, I would buy it. Hope that helps. GNG

I've been using Royal Purple for all my 2 cycle needs including snow blower (Toro), Chain Saw (Poulan Professional), small tiller (Mantis) for at least a couple of years. I mix it all at 32:1 and include a fuel preservative like Castle's Highway 95. While I know some folks claim they have had problems, I've run the mixture at 90+ degrees and -10 degrees and everywhere in between. I have not had any issues. I am not particularly tied to the brand - I bought it because it was a good value and from the literature it appeared it would run well in my equipment. It has and I will continue to do so.

There is no horsepower gain if you just add an air intake. You will feel a much better throttle response and I did gain about 0.7 mpg. Very easy to install, highly recommended!

XMC has higher cold cranking amps, and is heavier. It is the stronger of the two.

Only owning the 400, I can not make the comparison, but the rpm and power is noticeably different between the 1 and 2 setting. You can see it rotate faster, hear the change in pitch, and see the results on particularly thick or stubborn grass/weeds/etc. Having tried this out as a possible substitution for my Poulan Pro gas trimmer, I never plan to go back to gas (keep in mind I have only a small subdivision lot (~6100sqft) with a privacy fence and multiple landscape areas). I enjoy not having to maintain, keep track of, or charge multiple batteries. The 400 is a sweet piece of equipment.

My gas mileage definitely improved. More power and torque as wellI'm in canada so we measure in litres/100km. I went from 17-18 litres/100km down to 13-14 litres/100km. About 20-25% fuel savings. Biggest difference is in city driving and towing. They're are a lot of different models, make sure to get the right one for your tuck

I felt a power difference right off the bat. Looking back on it I probably should have got the one with programmable ignition timing.

Yes, I think so. The full synthetic racing oil will give you more lubrication and protection, especially at extremes. I noticed in my 2011 Kawasaki Concours which was already extremely smooth and quiet, that after I switched to 4T that it seemed to shift even smoother. I would recommend.

I am not an expert but I do have an above average understanding of engines and power. Ultimately an engine can only create so much horsepower based on the size of the engine. If you have seen a dramatic loss of horsepower which was not a problem before then you are better off spending your money on a proper engine diagnostic by a mechanic. This product, in my humble opinion, will not achieve the desired results you are looking for.

VW turbo engines require a European specification. I don't know it offhand, but I would doubt this meets that specification. I used to own a GTI and I used Mobile 1 synthetic. I think it was the 0w-40 that meets the European spec......

Anytime you increase horsepower in an engine you stand to abuse the tranny, rear-end, and tires along with everything else in the suspension. It really depends on your personal driving habits. If it's a Ford 7.3 you're driving, I saw a terrific increase in power with my 96 F350 with the 100 HP kick. A WHOLE LOT OF FUN. Would have liked to have seen better mileage but only have a single 4 inch exhaust out. My drive habits did not see an increase in mileage if not lost some. A friend of mine drives a 2001 or 2 Ford Exabition with this programmer and has increased his mileage 20-25%.
