Message Tried setting it to 900 unplugged. No luck.

I've been playing with the throttlebody adjustments for the past two hours. While maintaining sync, I've tried slow increments of making them more closed until the stop screws were level, then also tried to open them more. All while constantly resetting the TPS (to 0.44-0.46) and IACV (base to 850-900) every change I made. It made no noticeable difference either way.

I have noticed that if I slowly push gas pedal and let rpms reach 2K or so and let go of gas pedal, the RPMs do not dip as bad. Only if I push gas pedal suddenly (enough force to get the turbos going) then the rpms dip and almost stalls.
