Well,
I just got of the dyno and the care made 343 Rwhp @ 15PSI BOOST. Air Fuel Ratio`s were 12.2 to 12.5 across the board. However, when I went on a road test the car drove great and shifted at 6500rpms in drive (D) range. When I shifted the car manually with the hold button on, the car tends to bogs down when it comes to 6000-6500 rpm range. If you shift the car it will shift tight, but I thought that I could rev the motor to 8000 rpm. (manually)

Please let me know if anyone has experience this problem.

My mods are:

PFs Computer (purple)
PFs Intercooler, air duct and cold air intake.
98, Supra pump up-grade
B9ev cold plugs and 10mm magnecor wires
Petitt down pipe and Cat back exhaust

Is there a way to check for codes on the automatic transmission?

Thanks,
Andre
