Stage 2 rail
16g at 15psi-Want 20 but want to be safe?
Front Mount-Intercooler
2g-Maf
45-50psi-fule with B&k file ragualator something it's blue bolts on.
Some small thing.Any help be great and is yband a good gauge?

Better yet, with a boston accent.

I'll try to help a bit.

FUEL, for one. Please, just please spell it fuel.

yband= Wide Band, it gets its name from the fact that it uses a 5 volt spectrum in contrast to the stock 1 volt spectrum for measuring Air - FUEL ratios. Wideband is a MUST for anyone that is tuning a car, not having it at this point is a fairly poor choice. I would have had the gauge after doing the 2g MAF and 550 setup.

Turn fuel pressure back to 43. Get a tune. READ
Its wideband not "y". Its a type of gauge not brand.

Ok you will need some sort of tuning device (MAFT, AFC or DSMlink to name a few) to keep the air fuel ratio in check. The 2g MAF and the 550cc injectors almost cancel each other out but not completely. You want around 14.7 at idle and at wide open throttle you want low 11s. For these readings you will need a wideband o2 sensor and gauge. For 1g you want a 38 psi setting on your fuel pressure regulator. This must be adjusted with the vacuum line off. Keep the boost where it is or better yet just run wastegate pressure. Dont turn up the boost untill you get a tune.

14.7 around there at idle. WOT 11
