RB20DET Turbo, at revs it seems like its missing, low revs it runs well. Its in a VL Commodore

lol VL drivers...

we need more info than that dude, your problem could be ANYTHING!

Check for leaks in your intercooler piping, and try replacing your coilpacks. It sounds like the latter, under boost, shoddy coils will cause your engine to miss-fire.

Coilpacks are the most likely cause, especially if they are the originals.

Same thing happened to me with the RB26

$$Another possibility is it is just the factory turbo and running out off puff higher up? has it always been like this or just started?
