Jordo!

With the A/C running, in part throttle at least, the compressor is syphoning off some power which will make it feel more laggy.

There's a bunch of little issues that might contribute to these driveability foibles (but again, I still see more 09 complaints... hmmm)

1. Hotter ambient temps (summer...) means less dense air, means less power,

2. No throttle cable means less response may be tuned in to improve emissions, ecomonmy, etc.

3. All EFI'd cars tend to have some spark retard on tip in to control torque and minimize drivetrain wear.

4. Some power will be lost as oil temps creep over 230*F.

5. Some power transfer may be minimized when VDC is on to improve traction.

Most of those issues are tunable/correctable...
