Just got my car running again, with z32 maf, 850cc sard inj, adj [email protected](w/o vac), walbro 255, greddy type s bov, fmic, Emance Rom tune for 15psi, s14 t28.
After i first got it running, ~4days ago, it was really rich, i had some boost leaks due to multiple couplers, so i limped my car over to future fab and matt took care of me, redid all my intercool plumbing. I now have 1 piece hot and cold pipes. did boost leak test, and fixed all leaks so it holds boost no problem. However my plugs became fouled out due to driving with extreme richness. I replaced the plugs yesterday gapped to .30, still broke up bad in boost and still had afrs in low 10's even touched the 9s. Then i thought i may be blowing out the spark so i gapped it down to .25, that didnt help either. after pulling my plugs again i noticed, they were bkr5e coppers. when i was at oreilly i thought i had bought bkr6e coppers. would the bkr5's be too hot for this and thats why its running poorly?
Ive read multiple peoples threads from google searches trying to see what fixed their issues and really havent had any luck. I am going to be putting e85 in as soon as i getting it running normal on gas.( i have a separate tune for e85 which i can switch to, once its running strong)
Is it possible the 850's are too much for such little boost with only 15psi? i even tried running at just the stock 7 psi, however the car still breaks up.
Car ran great before i added the new injectors, maf and tune.
dont flame me too hard plz, just help
thank you.
