pulled the plugs yesterday...

and they were all white.... so that means i need fuel..... i was pretty damn sure that the stock injectors would hold up to this power but i guess not.... so i think i am going to change injectors out to some 22lbs.....

42 psi is stock so you can go up to 48 or 50

You won't. It's not like it makes a "holy cow" kind of difference in injector flow. Besides, your O2 will pull the part throttle mixture back to stoich anyway. And FYI, your plugs will always look clean as a whistle if you're just idling and driving normally becuase you're spending much of that time in closed-loop operation with the O2 keeping things in check.

You might want to drive around with a scan tool attached and see where your blocks learns stabilize at. Around 128 and you're about right on the injector flow. Low and you're rich. High and you're lean.
