Just wondering what kind of performance gains I should be looking forward to! I have many bolt ons as well. first time posting you guys

 

You will see trans shifts change and slight throttle response. Will you see as goof of gains with a custom tune from PHP or VMPtuning. Absolutely not. IMO i would have saved my money and got a gryphon from PHP or tunes from VMP.

Good sticky.
