Driving the car everyday and ran perfect all the time.
Drove the car hard and missed second and hit the rev limiter and car made a big backfire.
Keep in mind my rev limiter is at 7,000 not the JAM's 8,500
After this the car ran very bad.
The car runs perfect after 5000 rpm and pulls hard from 5000 to the rev limiter like it normally does.
But up until 5000 rpm even off boost there is no power.
The car isn't misfiring but holding back a lot.
If I leave the throttle off slowly the car gets very jumpy as I nearly leave it fully off as if it wants to accelerate.
Any idea's what it could be?
]I've got NO boost leaks and it's boosting spot on at .9 bar.
Running on a JAM ECU and CT9 hybrid.
Im so confused, golf/polo mk1 mk2 6n 6n2? Was going to go at this thiniking it was simple but the having problems with the rear and stuff is offputting. Any ideas what I should do, cant afford BC's or Meisters.
