i will bring a old thread up as i dont want to start another thread on splitfires etc
my problem is that my r33 miss fires from around 4800? thru to 7000rpm im guessing as the vct kicks in it starts miss firing mods are
stage3 slidingperformance hiflow
intercooler
3" from turbo no cat
walbro fuel pump
now ive only had the hiflow for about 3 days now,and since bolting it on it miss fires on all boost settings including stock 7psi, before with stock turbo it would only do it anything above 7psi so i could run stock 7psi wen it would carry on and could rev it cleanly... i was using .8 gap on my plugs so yesterday i explored and regapped the plugs to .6 they are a ngk plug heat range 7...now this has fixed all my miss fire problems runs like a dream on 7 thru to 13psi
now if since i regapped to .6 it fixed my miss wat was the weak link before that? coils? stock ecu? ive ordered splitfires thru sliding they sould be here within the week,im not fussed if they were my problem but i wanted to get them anyway b4 powerfc so ive got it all sorted b4 it goes for a tune..so have any of u guys got a clue as to why .6 gap runs perfect and .8 gap onwards it misses terribly.
sydneykid give me some info! u seem 2 be the man around here lol
