If I get a tune - Trifecta or other - what will it do for me?
- Will I feel more power?
- Will shift points be changed? I expect to get better MPG from exhaust and CAI as long as I keep my foot out of it.
- Will a tune also help my MPG?
- Which tune can I get an be able to switch back to stock if I need to take in for warranty work?
Thanks in advance for the help.

- from just the tune... no you won't really feel more power...
- I have Vince change my light throttle shift points. This allows the car to stay in a little bit higher RPM at light throttle, which give you a better feeling... you are a bit more in the power band. He didn't change the heavy throttle shift point
- However, he also FIRMED up the shift points! They are much better now! You can actually tell the car is shifting! He also reduced my torque management a bit.
- Don't know if it will really help MPG.. most likely not...
- Buy Vince EZ-Flash cable... you can then put the stock tune back when ever you need...
