Doh... I should have read closer. Makes 100% sense now.

Their site says:
"Developed with the average 3800 enthusiast in mind, this calibration has been designed and dynamometer tested and proven for the following vehicle modifications installed:
- 3.4” - 3.20” pulley
- Cold air induction system (brand not applicable)
- Cat-back exhaust system (brand not applicable)
- Premium fuel (91+ octane)"

So what if I plan on a 3.5" pulley, and don't have a cat-back system? I will have a PLOG, and a 3" DP. I do also have ready access to 91 Octane, but not anything higher than that currently...
