This problem is driving me nuts! I'm losing sleep over this. This problem has been so intermitten. The car drives like normal when driven around town, and sometimes, when I go wot or into boost, the car bucks and jerks. I just can't figure this out. I've checked the vacuum lines and all connections. Everything looks secure.
I've checked and regapped the spark plugs, plug cables, coil, etc. Looks good. Any ideas?

Mine does it when I'm a little lean. Turn up the WOT on the power tuner and see if it goes away. Saturday I had mine turned all the way to 1, but it pulled HARD!

Okay, I turned up the WOT on the Power Tuner to 1, and the car seems to run OK. I also reset the TPS Acceleration values to HRC's. Again, the car seems to run well. I'll see how it acts tomorrow because this is what happened last week, which I thought was a vacuum problem. Thanks for the tips guys!

Alright guys, I tried the above and, under normal driving acceleration, the car runs good. Also, if I accelerate hard (almost WOT) from 1st, to 2nd, to 3rd, the car will accelerate without much hestation. However, if I'm on the freeway or driving above 45-50 MPH, and try to go WOT, the hesitation and jerking will come back. Any ideas?

Same thing mine is doing. I think it's related to the Acceleration enrichment files, but I can't get it just right. It's like the fuel map is rich at idle, lean at cruise, lean at WOT, but rich when you apply the throttle at cruise. I need to spend a day with someone watching the TPS and MAP enrichment to get it dialed in.
