Welcome to the Stage 1 club [?][8)] So are you happy with it?

Oh yeah, I'm really, really pleased with how it performs! The main difference I notice is improved driveability and throttle response. I don't know that I can tell that it's making more power, but Stage 1 really makes it easy to move out quickly from first gear. Boost comes on earlier, too, and the car moves briskly and responds instantly to throttle input below 2500 RPM. There's much less turbo lag between shifts when going at or near WOT. Top end power doesn't feel that much different. All in all, it makes the car much easier to drive and very responsive. DCX should have used this PCM in the GT to begin with. It makes the car so much nicer and easier to drive.
The only odd thing I notice is that the engine speed increases by 200 to 300 RPM between shifts even with my foot off the accelerator pedal. With my foot off the gas, the RPM increases just by pushing in the clutch. I have to believe this is to keep the turbo closer to being spooled up, but I'm no expert.
One other thing I notices is that engine runs smoother with less vibration now. I have no idea why, but my EFI Triumph motorcycle also smoothed out when I had a performance tune uploaded to the PCM. So, I know I wasn't imagining it.
