DiabloSport In tune I2 on 3.7L Ti-VCT 2015 Mustang

Reviewed By Thomas H (COEUR D'ALENE, ID) Reviewed for a 2015 Ford Mustang —4/14/2017 11:55 PM

Very happy with my first experience with a tuner. Despite some negative reviews the tuner updated easily on my computer. Install went well and worked as advertised. Noticeable improvement in shift point, improved THROTTLE response, especially with paddle shifters. 93 octane tune provides a noticeable improvement. Stock program backed up on the handheld as advertised.

Worth every penny!

Reviewed By Brian M (Nashville, TN) Reviewed for a 2013 Chevy Impala —3/18/2017 11:30 AM

I love it! It makes my impala preform like I expect it to and more. I installed it the same day as a drop in K&N filter and my car sounds awesome. I deffinetly recommend this to anyone. It made my car fun to drive again. Not sure yet on any mpg +/- because I can't keep my foot off the pedal. I was worried about passing an emissions test but it passed no problem. Biy this, you won't regret it!
