No, the boost is not coming in. When i drive at aprox. 2500 revs and i hold the gaspedal to that rev, then suddenly he misfires and i can see the rev counter dropping for 0.5 sec and then again a misfire and then it's over.
When i'm driving at 3000 revs no problem it's just between the 2000 and 3000 revs with no boost.
Sometimes 2 days no problem then suddenly he misfires for two or 3 times en that's it no more misfires.
It's very strange and he only does it when i'm driving ,when the gear in neutral en then at 2500 revs there's no problem just under load he misfires.
