DiabloSport inTune I-1000 Tuner Reviews


Pretty good tuner

Reviewed By Thomas J (JENKINS, KY) Reviewed for a 2013 GMC Sierra —7/18/2015 9:13 AM

Truck feels much better after turning AFM and torque management off. Took a few days to really notice. Installed the 93 "hot tune" as well. Don't expect smoking burnouts or a Camero killer but the truck does feel better to drive. I recommend it just for the fact that you can turn off the factory restrictions and AFM, but for straight up power gains I recommend a custom tune. That's my next route.

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.
