Which size injectors are you running in your 408-436ci NA setup?? I am running Bosch whitetop OEM style injectors (from a GTP), and I get some surging at idle which makes me think the car is loading up in spite of the tuning we have done.
Please list your injectors.

Re: Which size injectors are you running in your 408-436ci NA setup?? I have the same as you. They are all white GM injectors for 3800 SC'd Monte Carlo part # 24508208 for my 427 C5R street machine. Also got a 340 Walbro intank. A/F ratio was 12.5 straight across the dyno to 6800 rpm.

Re: Which size injectors are you running in your 408-436ci NA setup?? PSJ: Are the offset values for the GTP injectors the same as the LS1 injectors? You may be scaled right, but not correcting the offset can leave you skewed at one end of the scale. I know the 30lb SVOs tend to cause the light throttle and idle to run rich if the offset is not corrected.

Re: Which size injectors are you running in your 408-436ci NA setup?? Joel I do not know but I'll ask Intmd8.
Apparently MTI uses 30lb svo's for all their big NA setups. Any MTI folks looked at duty cycle or pulsewidth during track runs?
Am I barking up the wrong tree here, I do notice if I get off the gas real fast sometimes it backfires or loads up. Car does surge at idle.

Re: Which size injectors are you running in your 408-436ci NA setup?? Delphi 37lb worked great on the old setup and they should be fine on the new one.
