DiabloSport inTune I-1000 Tuner Reviews


Suuuuuper easy to use

Reviewed By Jon L (BEAVER DAM, WI) Reviewed for a 2014 GMC Sierra —12/5/2014 8:11 PM

Easy as can be right out of the box. I even used a Mac and had no issues updating the device. Simply plug it into your vehicle after updating, pick your desired tune, let it do its thing, and done. Installing tune took less than 10 mins total. Capped off with the Diablo Sport OBDII cover. I plan to have a custom tune written by DiabLew once I'm done installing different exhaust components to maximize everything's potential.

Nice tuner.

Reviewed By Cody H (SODDY DAISY, TN) Reviewed for a 2004 GMC Sierra —10/9/2014 8:48 PM

Bought this tuner to go along with my full exhaust and intake. Made a very noticeable difference in power and the way the truck shifts. No mpg improvement that I've noticed, but not why I bought it. Would definitely recommend on GM trucks. Also allowing for custom tune is nice as well.

looks dont matter

Reviewed By oscar a (Norfolk, NE) Reviewed for a 2005 GMC Yukon —5/4/2012 7:05 AM

So I bought this tuner not knowing anything bout it. I was worried I might not know how to properly install tunes and mesure paeameters. Well after a while of research I found out how to installl tunes I tried the 87 octane tune. Right away I felt a huge difference my truck was awake my acceleration was different more responsive. So then I did more reseach found a guy by the name of lew or diablew tunes predator gives u the option to install custom tunes and diablo.com gives u the information you need to find people that can make a custom tune for ur car/truck. I found lew won't go into much detail but he tuned my truck with balls. There is so much thing u can do with this tuner if u have mods on ur truck a custom tune is for you. Or even stock vehicles can enjoy this great product.
