Spark plugs first check if they are ok and the gap is good, then check leads either check resistance with a decent volt meter or chuck some others on to try them, check coil pack or fuel pump maybe but its hard to say without seeing it in person.

Is it like a flat spot when you boost to a certain rpm It just wouldn't go any harder! If so I have same issue with a twin turbo vr4.

boost boost boost- Give us some ENGLISH. (Actual boost figure) Most of the time with them they are hitting the boost cut at 15 P.S.I. Don't allow em to boost over that figure-.

i had this problem as well, as it would hit boost at anything under 3000rpm, it would miss and fart and just carry on, anything over 3000rpm and it would run mint. what it is, is there is a sensor under the exhaust manifold, and that would have burnt out. replace that and its good as new.

They do not have them they run a CAS and have a coil block with an ignitor.

Interesting phenomenon!! If you have any form of sludge in your wastegate or turbo and your car still runs I will be seriously amazed! you don't mean carbon do you! either way that will not cause this problem

You wouldn't think so aye. Did though. Mitsi guys were pulling their hair out. No fault codes, nothing. Then the head mech walks in and. done.
