Guys - first off, I'm sorry about the Split Second thing... they first told me they could just dupe my tuning onto another box they'd sell, but I guess since there is a difference between 04-06 then that makes sense. In THIS case, I would just get the CP-e box re-tuned by someone local and forget the SS box altogether!
Also too bad nobody else went for the JP headers though - despite all my efforts in trying to get it all to work out, without being able to get hard numbers, people don't want to risk the investment for sound alone - and "butt dyno" results - LOL!
It took me MONTHS to get the tuning right, and I still ended up sacrificing a little off the bottom end (no more 2nd gear wheel chirps or burnouts off the straight line) but all in all better overall (noticeable) performance over stock (compared to the 07 rental Solaras I've driven at least) - but honestly, it's been so long since my ride was stock, I couldn't tell you just how much.
I do have Dynolicious set up and if I can find a good straight and flat stretch of road to test it on without a big load in the car, I will report my numbers. So far with minimal testing, I've gotten down to 15.1 quarter mile, but that was a loaded trunk and AC on.
*edit: one more thing, since my last tune and no real change in driving habits, I'm now getting between 22-28mpg average - lots of windy roads and downshifting plus hilly highway miles. One trip to Las Vegas I had a 20 mile stretch where I got 33mpg averaging about 85mph, but it was straight and flat.
