I just got back from Altered and they put in new Spark Plugs and Wires which I didn't think was the problem. My car is running a little better but Im still having the same problems. I figured out that my car shakes like a fuel cut at 4000 RPM and not when I hit full boost.... The mechanic who worked on my car, who used to have worlds fastest Supra, is almost 100% positive that its something w/ the VC1 but he doens't know to much about our cars so we left a message w/ Wyatt. We also checked for vaccum leaks and found none. Stan and I mounted the VC1 on top of the cruise control so that might of been a mistake.... Angel (dsmnt96) thinks maybe water got on it since the VC1 isn't protected much, so if worst comes to worst Ill just get a new VC1 and mount it somewhere else. Ill updated u guys when I know more and if anyone thinks it might be something besides VC1 please let me know. Im feeling better about my car now. I was just pissed that I was gonna have to drop a shit load of $$ into fixing it but it doesn't look that way anymore I hope. Thanks

I bet yer VC1 is hooked up wrong. Sopunds like you're not getting any signal from the MAP sensor.

Thats what I thought too
