Worth the $$$

Reviewed By Michael T (Chula Vista, CA) Reviewed for a 2008 Dodge Ram —3/4/2015 9:37 PM

2008 ram 1500 Hemi 5.7 my stock gas mileage was 13.5 mpg on the highway now I'm getting 18 mpg. I'll probably get even better Mpg on my first road trip end of this month. I feel the quicker response when I hit the gas. I have a noticeable amount more power. My truck. Feels like it shifts smoother as well. I also installed MBRP exhaust and Spectre Cold air intake. This CTS programmer is very easy to use. I live in California and its legal here the Diablo was not. it will pay for itself soon

It's cool tuning your engine

Reviewed By Matty F (NEWTOWN, CT) Reviewed for a 2009 Chevy Silverado —3/4/2015 2:56 PM

I used the 87 Octane tune, shut off AFM, and set the tranny to Firm setting. Everything worked as set. I found that the shifting from first to second was a little harsh so I emailed Mike at Diablotiune and he set me up with a custom tune for the tranyy. Great customer service!
