RB20 Cutting out issue

Recommended Posts

Hello, i have an RB20 Swapped s13 that has recently begun to cut out i have absolutely no idea why. It seems to drive fine nothing wrong then all of a sudden it cuts out its like the key has been turned off while im trying to accelerate it doesnt even have to be when im coming onto boost it can happen just randomly but normally between 2000-3500rpm. if im at a complete stop and it begins to do it, it sounds cammed and wil rev high then drop down to the point of almost stalling then rev back up then do the same thing. When its doing this i cant give it any accelerator at all it just bogs down, ive replaced the CAS twice, checked TPS, checked coilpacks, compression was fine. I have no idea what this could be, if anyone has any advice that'd be great :( things to note as well it has an IACV delete and stock ecu.
