Also the pcm will still see boost via the map sensor, but it'll only see what you want it to see (afc comes into play here) Any #'s on the afr's or anything with 20+ psi? I'm assuming your on the stock fuel set up (or stg 1 based on your year) I have noticed from my personal experiance, that a stg 1 pcm will pull far more timing if it thinks anything at all is wrong then the stg 0 pcm. That being said stg 1's fuel maps are more agressive and gives you extra fuel to play with. Now if your running a return line, take my last statement and chuck it cause then you have as much fuel as you need. keep in mind also that our cars stock have been known to run 1700+ egt's so leaning that out even more just makes it even hotter, which leads to stuff cracking... I'm really interested to know what what the afr's and egt's your running with your set up.
Wow good very good..you have been studying I have RC750cc injectors/Perrin Big Bore fuel rail/Return system w/Aeromotive FPR and Walbro fuel pump/SAFCII-answer your fuel question? My car runs very rich..partly in due to the LARGE AMOUNT of fuel upgrades w/stock turbo..pulling back about 28% duty on injectors....But I did all these upgrades 1st..in part to see what the stock turbo could push with all supporting mods(minus NO2 or Alky inject) then I ordered the Turbo upgrade last...But trust me..you can push over 330WTQ with this setup w/no prob...regardless of what you have heard or being said..I been doing it for about a year daily driven
