Strange issue at wot??? Alright in a nutshell I put a ported throttle body on tonight and went for a quick ride and at wot the o2's drop right down to like 75mv. They used to hold 890mv or so. Does it in 1st n 2nd later in the upper Rpm's like 5k+ but seems to drop off in 3rd real quick. The knock retard was the way I figured something was wrong.Double checked maf tps connections. At cruising speeds o2's appear to be switching fine. I can post a log if need be. Was just lookin for some quick suggestions to something I mighta missed. Also at wot tps voltage reads 4.65volts. Could that be to much? Hopefully I posted in right section. Forgot to mention car is a 99z28 ls6 intake slp lid ram air hood egr & air pump removed also
