question before i go to far

[lilrocket]

ok ive been a lil busy trying out different stuff on my 98 so far ive gotten a mps 3.0-3.2-3.4, headers, removed the cat and res replaced with a 3in straignt to the factory mufflers, 160 stat, dhp pcm,,intank 255 pump cia ported the sc and tb removed some weight and added a lil back lmao ok

before the headers and porting i ran the 3.4 with 1-2kr
put the headers on dropped to the 3.2 pulley with 0kr
put the 3.0 pulley on and with pump gas i have 1-2kr and 0kr with fuel mix but with the 3.0 pulley the fuel pressure drops like 2-3psi at wot cant b good wat can i do to keep this from loosen too much fuel psi or is that fine bn its so low i have a set of 42lbs just havent got the chance to swapem

KR doesnt mean your good. AFR and Timing are just as important. Anyways you need a larger injector. Like the 42's you have. You need to tune them aswell

You aswell need more mods. Like a cam or intercooler to run what your trying to run

will keep in mind i know this things running stupid rich right now for some unknown reason my gas mileage sucks ill put the wide-band on it this weekend and check im running the 3.2 for now i checked the plugs and they look pretty good as well thanks i so wasnt thinking of the af and timing lol didnt think of the af just bc its running pretty rich

parts dont make knock go away, TUNING does.

I think you will get better results with a tune than dropping pulley sizes.
