installed the off the shelf 87 performance tune and it really tightened up the driveability. Turbo lag is much shorter now. Excited to look at a 5 Star Custom Tune!

 

Better dig in to the 93 octane!!! 87 is childs play

 

I just did the same steps with my 5.0 but mine had a strange gear searching aspect in 10th that when I applied more than 2% throttle it would downshift on the canned tunes. The five star custom tunes really were night and day. I second Ice with the 93 octane tune.
