Hello, I have recently upgraded my fuel pump, hotwired, TT chip 5.6 to run on 93 octane up to 18psi boost, an adjustable wastegate and regulator, 42lb injectors and scanmaster. My question is when I start car the O2 millivolts are at only 400 ish. When I go for a ride they go in the 600s, sometimes 700s, but am told they should be at 720millivolts at idle. whats up, or what do I do Im dumbfounded. The fuel pressure with line off is at 43 psi as directed.
Any help would be appreciated
