Tuning my TTA.

[TurboJoe89TTA]

I installed a Thrasher chip. When I give it 1/2 to 3/4 throttle it seems to accellerate faster than WOT throttle. Boost seems to go off at 1/2 throttle. Sending the factory guage over 20 PSI. I know these guages are not all that accurate but... Plus the idle acts kind of funny. Smooth, then sounds like it is going to stall, then smooth again. I read the Thrasher instructions and it said this could happen if the AIC (air idle control was not set properly. My gas is 3 years old too! I ran it down to 1/6 of a tank then fueled with 2 gallons of Mobil 93 octane. I figured I would mix a little higher octance then refill at the empty mark.
I do have a direct scan 1.5 version but I do not know how to use it. I do not have a scanmaster. Help.

To scan the car you must have a scanner. You are tuning blindly and the reason your car is slower at WOT is because it is knocking HARD. You need to get some fresh gas in there, lower the boost, and get your idle parameters first.
