Easy install and start up

Reviewed By Darrel H (PASO ROBLES, CA) Reviewed for a 1999 GMC Suburban —8/22/2014 5:45 AM

It was as advertised. Easy to hook up and so far works perfect. I was able to do a milage tune , then a performance tune and could feel the difference. Also cleared an engine code. Excellent piece of equipment.

Great Tuner with only 2 drawbacks

Reviewed By Chad A (Renton, WA) Reviewed for a 2006 Chrysler 300 —1/20/2015 3:41 PM

This is a great tuner with many options. My 2006 Chrysler 300 SRT-8 felt like it was idling just a bit off for my taste. This tuner fixed it and made it purr like a kitten. I did not really notice any high RPM power improvements however it does accelerate off the line a lot smoother now. This was almost a deal breaker. You have to pay $120 to get a vehicle specific tune vs bama = free AND are there are ZERO options to adjust shift firmness (You have to buy another $260 tuner to do that).
