I have only had my PCMofNC tune installed for about 2 weeks now and I have to say I am very impressed. Throttle response is much improved at low and mid range RPMs. The shift firmness (Level 2) feels great and down shifting is much improved as well. I think increasing the rev limiter has an effect on this.
I caught PCMofNC's Memorial day sale, $139.99 for the tune (Mailed my PCM to them) plus the cost of shipping. There service is quick. My PCM arrived Tuesday morning and it was back out in the mail the same afternoon. After installing the tune, I definitely wish it would have been my first mod on the TB. Well worth the money.
If you decide to go with PCMofNC, after you purchase your tune on their website, you will have to fill out your tuning order sheet. It is about 7 pages of questions about your vehicle and whether different components are stock or aftermarket. Below is my tune.
Shift firmness- 2 Moderately firm (Choose between 1 and 3)
Fuel Octane- 93 (Choose between 87 through 93)
Speed limiter- Removed
Rev Limiter- 6000rpm
Aftermarket CAI- Yes
Aftermarket exhaust- Yes (They said with the resonator cut off and replacing the stock muffler with a Flowmaster, that would be considered aftermarket)
Do you tow- No, 80% torque management removed (Can tell a huge difference)
Those are the main changes I made, everything else that I did not list was left "stock" on the order sheet.
