I have FSWerks stage I&II, gt28r turbo, on my stock motor and ATX. I was running 8psi for about 2 years (10k miles) and never had any problems. Would bump it up occasionally to ~12 psi and my tranny wouldn't like it to say the least. TC would lockup and it would basically feel lk a MTX that wouldn't shift into the next gear. RPMs would go up but the car would not accelerate. Keep it mind this was only on hard acceleration from a complete stop. Replaced the stock valve body with a Lentech valve body, brought boost back down to 10 psi and have never had a problem since (been about a year now). Also have the ford racing (TCS) torque converter I planned on installing and raising boost but never got around to it.
