Big

Reviewed By Craig B (Houston, TX) Reviewed for a 2008 Chevy Suburban —7/24/2008 8:23 PM

Big performance increase. It shifts really hard. I am not sure if I like this or not. Gas mileage increased about 5%. I was hoping for more.

New life for an older truck

Reviewed By william s (WINSTED, CT) Reviewed for a 2004 Chevy Silverado —5/22/2016 5:38 AM

I bought a new rv last year, and was unhappy with the trucks pulling performance....so i did some research,and found a tuner would do the job....i did not need all the bells and whistles..just something to change the timing and shift points....this unit was just the ticket....and it was on sale.... cant beat that....have set it to tow mode and it made a big difference....i live in new england (lots of hills)..and no more overreving to pull them...my truck works within its power band .
