Turbo Problem?

[shoopice]

I have a 28,000 mile TTA driven currently about 300 miles per year. I took it out the other day and it ran fine until the boost engaged. It seemed to run up to about 10psi and then the acceleratioon cut out real bad. It seems like it wants to continue as it will jump up to about 12-13psi only to cut out again. its almost like it is stumbling. It runs fine other than that. Revs fine in nuetral etc... The car is completely stock. Any ideas out there? Any assistance is greatly appreciated!

coil pack, MAF, pug wires, fuel pump. I'd start with making sure these are all new or in working order. My friends GN did the same thing and it was a shot coil pack. It sounds like spark or fuel obviously, but sometime the MAF goes bad.

THANK YOU FOR YOUR REPLY. I ASSUME I HAD BETTER START THERE. ARE THE COIL PACKS STILL AVAILABLE FROM GM?

Also, do U have a engine tiedown ? I removed mine because it was rubbing my AC line and wore a hole in the line. I'm having a WOT cutout problem also, and don't know if maybe part of it might be the engine twisting too far over w/o the tiedown. I may see if I can reinstall the tiedown so that it doesn't rub the AC line.
