Hi All,
Okay did a search on this and found heaps but none that really has the same issue as my car so, I got a dual stage boost controller installed a few weeks ago, got it set at 13psi, car is stock ecu only other mod is pod filter dump pipe and 3inch exhuast, the mech said these cars have a fuel cut at 14psi so if car feels like its missing its the fuel cut out cutting in, might happen at night when its cold as it might spike. So try it out one night and sure enough it starts to miss. Checked psi and was spiking so turned it down to 12psi, still happening, thought then maybe regap spark plugs, so now gapped at .8mm still doing it so turned it down to 11psi and still missing so went and got new plugs and gapped them at .8mm got copper NGK BCPR6ES still f**king happening!!!
I can progressively put my foot down and it won't miss but feels as though its being held back, its a constant miss not eradict, like its every couple of seconds and its the same all through the rev range, I now hav it at 10psi and this ain't much better than standard although is a bit quicker, but am i hurting the car somehow???
I'm at a loss people so any ideas would be much appreciated
Cheers Adam
