Thats also good to know and I will certainly consider this for the stock motor. Although they are more expensive to do, I much prefer standalone programmable. Anything will make HP given a competent tuner, but once you experience a Haltech ECU in the right programmer's hands you never want to use anything else. Even if the two methods produce similar HP and Torque, the aggressiveness of a properly tuned Haltech is beyond belief. Thanks so much for this valuable info on the year and ability.
