Who is the local tuner though? Has he done 3800's before? What program does he use?
If your dropping to a 3.4" then you can run the PCM on a stock pulley and it'll be fine...they are programmed for a 3.4" setup though. If you don't plan on modding past that there is no point to skimp there...just get the mail order PCM.
It says full exhaust in your sig...is that not headers?
Therefore...you liar...that isn't FULL EXHAUST![]()
