i just installed my wideband and when i start the car i am lean at about 16-17.5 but when i give it a bump with the throttle it drops to about 14-15 at idle. if i don't burp the throttle it will idle lean. i have a custom chip burnt on the dyno. i had 19 lb injectors when the chip was burnt. i have changed to 30's with a pmas velocity maf. i have a 302 with gt40's 1.7 rr,e303,cobra intake and 70mm maf and shooting a 125 shot. my chip is a two position with a na and nos tunes. i just took it for a rip around the block and it looks okay to be about 10-12.5 at wot. im assuming the goal of 14.6 idle with 12.5 at wot is my goal.
