DiabloSport 8200 inTune i3

Exactly how I thought it would be, easy to use, added good power with the 93 octane tune and trans shift firm tune. Transmission runs cooler, engine runs way better and feels and shifts right on point.

Worked just as described..

-10 stars if that was a possibility. Please do your research before you buy. This thing completely screwed my truck up. Everything worked pre-tune. Now the only gauges that work are the oil pressure and voltage. My ac doesn’t work, and neither does my radio. I sent it back to Holley they reprogrammed my pcm and sent it back. It’s doing the same thing as it was before. I called them and of course it’s not their fault or the tuners fault, so just like a bunch of other people, im left holding the bag. DO NOT BUY!!!!!!!

It works! 2003 Silverado. I am running the 87 octane Standard Tune. I have modified exhaust and intake. When I first got to give it some throttle after following the instructions exactly it really put a smile on my face when it shifted right away and climbed in speed. 👍

If you're on the fence about this product just do it! I have a 2004 dodge ram 1500 5.7 hemi. Before loading the Diablo 91 octane tune my truck had slow sloppy shifting and throttle response was so slow. At cruising speed I had to nearly floor the pedal to get it to down shift and it just felt bogged down. Now with the Diablo tune the response is instant!! It's almost scary. My truck has alway had good traction on dry and even wet roads but now it will light the tires up on both. I've had to change the way I drive to keep her planted. I will say that the improvement was not immediate. It was probably the 3rd day after loading the tune when everything clicked with the tune. The most beneficial adjustment was the throttle response adjustment option. It gives you the option to adjust response 1% to 20%. Do the 20%! It will make you fall in love with your hemi all over again! Go lightem up!! (Update) Can't express enough how important it is to make sure your engine is running cool (180 thermostat) after loading the tune my truck was running waaaay better especially in the mid to high RPM range. But I noticed my motor was still running around 200 degrees even with the 180 thermostat (bought from local auto parts store) so I ordered a Mishimotto 180 thermostat and installed it today. Mercy it was like adding a tune to a tune. Now I'm truly running in the 180's. The power is across the board now and just light the tires up dangerous. Before loading the tune make sure you have all other mods complete first. The power of the tune is dependent on other mods like thermostat, CAI, exhaust.

I’m a nematode. But this was easy to use, feels strong and not cheap in quality, and I was able to do so much. Change the rev limiter, recalibrate the speedo for my 34’s, put a firm shift tune on, do a DOD delete, and put on a little MPG booster, super functional. I do wish the screen was a little brighter, I had to hold it like a foot away from my face lol.

Installed this into a 2009 Silverado with a 5.3. I updated the unit first and set up the wifi before I went to the truck. I also registered the product automatically at that time. The next day after work sat in the drivers seat and plugged it in. I installed the 93 tune, firm tranny shifts and removed the speed limiter. The programmer backed up the original truck settings before it installed the new settings. The check engine lights went on and off, door locks went up and down and it stopped. The tuner said it's finished and enjoy the tune. I went back into the advance settings and under ECU I turned off the DOD, it reprogrammed it for that. Same procedure with the truck dash lights blinking then I get the your done message on the tuner. I unplugged the unit and fired up the truck. No idiot lights and the truck was running smooth. Took it for a spin. No issues. I stepped on it and my head bounced off the head rest. Holy Smoke this truck is alive now. It's faster than before. It put a smile on my face. It's worth the money. I'd recommend this to anyone.

This thing is dangerous. Had to Tow a car and pay to have my friend Tune professionally. Full custom Dyno-Tune $450 … this ended not moving in the middle of tune. Knew it was going to “Brick” the car. Craziest part was 3-4 hrs in (mainly trying to push a button) it randomly selected gear ratio, made an adjustment, and then saved itself. I was so angry after not working or responding for a solid 73 minutes I didn’t even care anymore and just refunded things for this thing and his service, compensated his time, paid his tow, paid for my buddy to Tune his car and realized this little device cost me $1,678.23 in total. Believe all the reviews warning you and the ones that aren’t, likely just don’t know to expect anything better I assume. It’s really unbearable.

Got sent a lemon i love diablo tuners but this seller sent me one with a messed up touch screen

This causes my engine to ping. (Knocking sound under heavy load) It has not given me any better performance gain, or fuel mileage. Waste if money. Seller would not accept a return of the product. Buy another product elsewhere.
