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.

It does what I expect and more

Dang. I didn't realize there was a 500 character limit. So I will keep this short and sweet. Power 5 Ease of use 5 Tuneability 4 Instructions on what does what 3 If you don't care about your 0-60 times and yada yada buy this tuner. Oh! Do NOT adjust your tune if you have smog/state inspection coming up. They don't tell you that if you adjust parameters you will fail. It took about a week for my truck to go through the "GM cycle". Great buy, autoanything rocks

lots of adjustments

Reviewed By Daniel B (akron, NY) Reviewed for a 2014 GMC Sierra —3/25/2015 3:07 PM

pretty nice tuner for the money. a bit complicated without much info sent with the tuner to know what some changes are. iv had three different Hypertech programers over the years and feel this has a more noticeable power improvement.
