well i have a 98 gst (essentially stock) and here is my problem. while driving say in third gear and i step on the gas at around 3000 rpm the car will rev faster to 4000 and then fall back to say 3500. Its not like a clutch slipping either. the car revs faster and pulls harder then the rpms drop off to where they should be. according to the boost gauge the boost does not increase any once at full boost. can't notice through 1st and 2nd gear because they are shorter but in third, fourth, and fifth it does this all at about the same rpms. don't know whats wrong. the car feels like it is pulling harder for that short burst, you can hear the engine rev faster and the rpms go up and then drop back down. then the car continues as normal to redline.
any input on this would be great thanks,
