Have you checked all the intercooler pipes and joiners?

Give that a try sounds like a leak

Sounds like crank angle sensor to me. Try a different cas and see what happens.

tried both no go it feels like coilpacks are crapping them selves as soon as i give it some but i got splitfires in

check your afm and also youur O2 sensor...sorta had the same prob and i changed afm and it fixed it for a bit and then i scanned my car and it said the O2 sensor was buggerd so i just disconnected it and now it runs a dream..hope this helps.

yo man this happened to me, what mods are you running on your car?. what you can do is, first clean afm like said above, then check coil packs for any cracks, then make sure all spark plugs are good, and have got the proper gapping.. If it still doesn’t work and if your car has a decent amount of mods, change the fuel pump..

i had the same problem a week or so back, where my car would hit 3.8k-4.2k and start back firing very loud and the car wouldn’t go, so i put a gtr fuel pump in and it fixed the problem so it could be a fuel pump issue

Good luck man
