Tuning advice

[SlowChild3]

Hey guys.
I got a few questions about tuning my car...
Well I just installed a Walbro 190 and ran a log. I'm starting to lean out at 4500rpms at 86V (not droping below to redline) on the o2. Not knocking untill 88V, 9-11 counts. I noticed my Injector Duty is running no higher than 75%. As far as I know the injectors are stock. I'm running 15lbs, I've read that most cars start maxing the injectors out around 15lbs. So my question is are these stock injectors and if so can I tune with my safc? Or will I be hitting fuel cut befor I max them out? Thanks alot guys.

Do they have blue tops? If so, they should be 450 cc injectors. You can tune them with the SAFC as well, if you wanted.

Did you rewire the pump?

Post a log.

A log would help big time. 15 psi with a 14B, you should be around 85-90% duty cycle. If you have 450cc injectors, there really isn't any need to tune them. SAFC is to compensate for larger injector sizes, you probably won't gain anything by tuning 450's with it. Get some 550's at least, then you will feel a big difference.
