ok i just get my car out of the body shop after being without it for 2 weeks... i head down the road and start a pull from about 25...just because i missed it.. and when i get to around 3000 RPM i hit JERK city... my car just jerks very badly like the boost was cutting on and off.. and i re-state.. VERY BADLY... i did it a few more times to just see if it would do it again... and it does.. always around 3000 RPM and with Big E316G it reaches full spool around 3000-3200 RPM... im wondering if there is a leak in the turbo or somethign with the boost... any help???
