ok so i finally get my car back from dogbox after they put in a trans.....and i think everything is goin to be great..... and im shot down dogbox had nothing to do with this issue i stress that. the last time i drove my car before the trans completely blew when my car goes to make boost it falls flat on its face.....just starts breakin up and surging in and out of it....it needs to be retuned i know this but before the trans went it was fine....even though runnin rich. i pulled the plugs and they were fouled bad i tried to clean them and it runs alittle better but i cant even rev it past 3000 its starts jerkin. its got a reflash or eprom not sure t4-t3 60trim pte 780s adj fuel press reg full custom exhuast with a cat i think a wide band after it.... fmic mishi rad.. manual boost contrl. its pissin me off..nothin changed i have no clue wats up...and now the check engine light is on im doin the plugs tomorrow is it possible that fouled plugs cause this problem? i have heard that when the spark is weak the boost can blow it out i dont know if thats true....need advice asap... thanks guys

Try testing your TPS. Sounds like it could be a culprit to that issue.

Check for a boost leak.

Any new info? Did you install new plugs? Do you have a way of pulling the code? That would really help with a diagnoses

It does not say in your profile what your using for fuel control. Sounds to me like your 780s are just dumping too much fuel, with maybe a boost leak. Do you have a set of stock 450cc injectors or something to control them 780s?

for fuel control it has a reflash or an eprom i didnt pull the ecu yet to check. im gonna do the plugs asap....i was gonna limp over to autozone or one of them to scan it just to see wats up....a boost leak will cause it do act like that??? its weird....i can hit the 2 step no problem.....and the antilag....acutually i didnt look to see watboost it makes when i do...crap ill look for leaks asap i hope thats it

Fyi autozone doesn't pull codes any more.

I just figured out what it is...its hitting the anti-lag while moving...if i go slow enough i can make it past it....it hit the 2 step also. but if i go slow enough i can make it. the check engine light is on and the speedo works so i don't what is causing it. Is there a speed sensor that might be bad?? Something is not letting the ecu know that the car is moving but the speedo works.... I'm stumped...anyone ever run into this??
