i read that the stock ECU makes it run really rich above like 4K. wulda fuel controller, like the apexi safc-ii let u lean it out on top a bit to get some more power? or does the stock ECU have complete control?



The previous owner removed the cats and airpump, so the 5th and 6th ports are wired open. what are my options to have my ports open and close?from what i understand(which is probably wrong) if i got the RB header and presilencer, i can hook a line to the presilencer so that my 5th and 6th ports open?

I won't try to help with the 6-port question, since I have no experience with n/a's.



But...



The SAFC will allow you to lean out the midrange and high end, and it should make you faster. Make sure you have some way to know what your A/F ratio is before you start messin' wit it. When you blow your engine, you'll know you went too lean!
