My 2003 S was rebuilt as a 3.6 with LN Nickies. I have a custom Softronic tune made for the 3.2 bored to 3.6. After engine break-in, the car was run on a chassis dyno, the results were sent to Softronic and they made some further adjustments to it. My recollection is my shop said I could stay with the stock tune, but I elected to get the Softronic tune. I stayed with the stock throttle body and intake plenum, and my headers are a more restrictive since they have catalysts. If you're going to have move open headers, a 987 airbox and MAF, bigger throttle body and matching intake plenum, you'll probably want the custom tune.
