bogging down

[HIGH_PSI_GST]

for a while my 97 gst has had a problem with bogging down. what happends is i will start moving and when my turbo starts to spool sometimes it feels like i got about 20 people in my car. it just gets really slugish but then if i let off the gas then get back on it it goes away...... i dont think its my turbo because its makin plenty of boost. but its weird because sometimes it will do it and sometimes it wont....... anyone had this problem before?? i was thinkng clogged injectors but idk. please help. also i have a weird kind of grinding noise coming from the passenger side of the motor when ## sitting in the car. it doesnt make the noise when i rev. only when i i start to go a little bit in 1st and 2nd gear. i just had the transmission replaced last week so that might be the noise but im not sure... please help thanks!!

For the first problem. Check all your ICP for leaks, I had a cut in one of my couplers and it did the same thing. I would boost up to a certain point and it felt like i hit a cow. Also what are you tuning with?

Opps, i just checked your profile and you seem to be stock. So yeah make sure you check for boost leaks. How much boost are you running?

i got greddy IC piping, boost controller, fuel pressure regulator, cam gears, intake, exaust, BOV, oil catch can, and plug wires. im spikinig 15 psi. and i used to vacuum at 19psi and now im vacuuming at 13 or so. but i read that when u get after market cam gears it makes u vacuum a little less than with stock cam gears
