+1 Ive had a hypercrap and superchips and now run custom tunes on everything. If you want an example when my truck was stock it went 15.8. With a hypercrap it went 15.7 with a loss of 2mph, with a superchips went 15.8 with 3mph gain. I had a custom tune done and picked up 7 thenths to make it go 15.1. Gained all that with just a tune.
