Have a over sized alternator, with a 2000 watt amp. Use this to monitor the voltage of my car. Works well, shows when things are running low much better than the factory Chevrolet gauge in which you can never really tell.

This gauge was installed on a 2012 Yamaha drive cart and works fine, however, based on neck of the gas tank, the gauge veil not show completely full when you put as much gas in the tank as it will hold. It shows 3/4+ full. Minor inconvenience. It is still a lot better than having to look at the tank wall for fuel level. Shipped and delivered quickly. Good vendor, good product.

Gauge is great due to the color concepts make it easy to see and read when mounted below dash. Gauge also mounts easy center lower of dash.

...and that's what I got.  I keep pretty good records so the fuel economy would have shown up.  Of course, I probably have my foot in it more now since it is pleasantly louder than the stock setup.  It's not offensive and my wife wouldn't have noticed it if I didn't mention it to her.  It really cleaned up the engine bay to get that giant box out of there.

Wonderful product, added a bit of electrical tape to make things look a bit better. Didn't have to remove anything from the housing to get it in my '04 Colorado.

Please know, however, this does not address the root CAUSE of the issue. Your old resistor would burn out because of a faulty ground. Under the hood above a fender, there was a ground box I removed and scratched a bit of paint off to get a proper ground to make sure this doesn't happen again. Why did Chevrolet think it was a good idea to ground to paint? That's anyone's guess.

Engine pulls slightly harder/smoother near redline, where it was running out of breath before.  I do not believe that this is making more power per say, but feels like it smoothed out the power a little bit all around.  This is MUCH nicer solution than the ebay intake pipes, as it retains all of the OEM components of the car, which raises the resale value.

Very simple to get set up and running. It only has 2 factory tune for my chevy truck (87 oct and Diablo(91 oct)) I thought from other pictures and video i saw that there were more.

The diablo tune does seem to get me better over all millage when using cruse control. If I race around town I noticed that i can use more gas, but that is just my heavy foot.

I got this tuner mainly for the custom gauges in that way it is great!

Although we don't get a LOT of rain here in Arizona, even 1/10th of an inch showed up on the gauge.......I am happy

Having trouble putting fuel in your tank?  Good chance this is plugged.  High quality GM part.

I was surprised by the improvement.  I bought a lifted 2006 Ram 2500 4x4 diesel 6 months ago.  The steering wasn't great but got worse since.  One mechanic told me the ball joints were bad.  Then my tire guy did a quick check and said biggest problem was the steering gear. My tie rods are firm, lower ball joints firm, upper ball joints just slight wear.  I had intentions on changing the steering gear and adding the stabilizer this weekend.  After checking the gear myself I decided to first try the stabilizer. My steering gear had very little wear.  Glad I did. I could tell the difference pulling out of the drive way.  I do still have some play, but it is much improved.  My exam did show the drag link ends had some wiggle. I will change those next.

Van was idling up a little, swapped this out and seems to be running better.

It should be noted that the part came with the float arm attached on this particular unit even though one of the images on the listing shows that it needs to be assembled first. Mechanic cleaned out tank prior to installation and verified part was the correct one for my truck before installation. The part was installed and 5 gallons of fuel was added, poured in from a 5 Gallon tank I brought with. The ignition was turned on and the fuel gauge showed just over one quarter of a tank. This vehicle has a 35.7 gallon tank so this reading concerned me.  After driving for a few hours I noted the tank level dropping just slightly however when the gauge read just below one quarter I noted the vehicle starving for fuel as I accelerated around a corner. I had an additional 5 gallon can so I continued to drive in an attempt to confirm fuel low indicator would still perform correctly.  At about 1/8 of a tank the vehicle was starving for fuel during acceleration while not turning and then within minutes even light acceleration would cause starvation. I was able to idle into to a gas station but the vehicle was essentially "out of gas". The Low Fuel warning message never displayed on or chimed and although close, the needle never indicated true "on the line" Empty (see image below) After discussion with several ford technicians I have been advised that during normal driving on a level surface the low fuel chime and display warning should appear when there is approximately 2.5 gallons of fuel remaining in the tank. The gage was functioning normally as well as the low fuel chime and message display before this fuel pump assembly was replaced.  I am sure of this because it had worked several times in the past including the day I dropped it off for the fuel pump assembly replacement.  I was able to get 35.2 gallons in when I filled the tank and the truck has performed normally since the fill up as well as it indicated just over the Full line. I am including a video that shows the following: During acceleration the tach rises to about 3800 rpm indicating hard acceleration then drops suddenly indicating the demand for fuel was greater than the supply available. I kept my foot on the accelerator at the same position, during this time (due to inertia) when starvation begins, fuel rushes back to the fuel intake and acceleration begins again with similar results.  Please note you can pause the video and see that the fuel gauge shows approximately 1/8 of a tank of fuel remaining. The movie and image were taken 12 minutes apart. As I said I have completely fueled up and at the time of this writing I still have over half a tank. I will update this review if it begins to function normally however if there is no update, that indicates I'm still driving around with this piece of junk and still running out of fuel before the gauge even gets close to empty. I regularly tow a camper that changes my fuel mileage drastically depending on road conditions idling in traffic and hills so watching the trip odometer cannot be used as any indication of how much fuel is left in the tank. I do understand that I can return the product but if I had the extra $200+ labor to put another one in I would not of purchased the $69 unit in the first place.

The previous owner of my 1953 Chevrolet truck put a 'high performance' coil in the truck.  It was rated at .7 ohms resistance and something like 40,000 volts.  The problem was that the ballast resistor in series with the coil was still not enough to reduce the ohms running through the points, resulting in the points welding themselves together... not good.  ANYWAY, switching to this coil with 1.5 ohms provides enough additional resistance to keep the points cool, and the voltage output through the spark is fine.  My truck has never run better and the points may outlast the truck now.

My truck (second vehicle) has headlights that flicker sometimes, so I bought this to install in the cigarette lighter hole, to watch the system voltage, which dropped to 12.6 at one point with my lights on at idle. This tells me there is definitely a problem with a bad connection or more likely an alternator which is failing. Very useful to be able to monitor system voltage to know what is going on! Mine is connected at all times so I can see resting battery voltage before start up which is good to know to determine battery state of charge. Power draw is so low that it is irrelevant.

Holly crap, I think I just bought a new car, I do realize it is a new a car but being a 2013 Dodge Charger RT, I've had it for 6 months and it felt pretty slow. The car is now a powerhouse and I can turn off traction control, I am starting to feel a lot better about my car and it got rid of the factory transmission tuning that wouldn't allow it to down shift above 70 mph, of which really pissed me off, Thank you Diablo Sport!

Put 8 in 96 GMC serria, works great but the older gauges aren't the best at evenly distributing the LED light. The lights themselves are flawless

I picked some up at the auto parts store the other day. V8 chevy with afm. Of course with over 100k on the motor it would tick at start up. This is the second day I've had it and it's 2 for 2 without the cold start up tick. I'm sold seeing as how every cold start had the tick for a few seconds and the 2 after using it didn't.
