Lew has been working on my custom tune for a bit now, and let me tell you...its Awesome :twisted: . Absolutely worth every penny. It feels like a completely different truck!! Lew has the best customer service Ive ever experienced. I sent him my first data log at 11:00 on a Sunday night... He had my custom tune sent back to me in 15 min!! Same experience on the second round of fine tuning, Sent him my data and had a tune in my Inbox within 10 min.
I was wondering if anyone has ever done a before and after Dyno testing with one of Lews tunes? Im expecting it to be a pretty significant difference, but I havent been able to find a forum with any real number so far for the 5.3...
