Well were trying to fix my buddies SR swapped 240, hes got a T28 with a supra wastegate. Theres one problem that we cant solve, the boost holds fine until 6000 RPM but then the boost is dumped and theres still power up to 8K or whatever but no boost, were could we look that may be causing the problem.

I had a similar problem with my s15 t28....boost would die off, then i got an HKS wastegate actuator and the problem has dissapeared.
