^^ Except know you have Vortec heads and a large carb style plenum I would do both TPS and MAP AE values. I would multiply all but the lowest values in both tables by 1.5. I leave the lowest values alone because it seems to do weird things to the idle/off-idle tip-in if you
Thanks for the replies guys I have been out of town for the past week so now I get to play around with this stuff. Thanks again.
Found this thread and wonder if it pertains to the lean stumble I have on acceleration with the single plane intake TBI I'm working on dialing in.
My stumble seems to mainly happen on 3rd gear shift of 4L80 when on it about 40%TPS, though it will stumble in other acceleration conditions when the throttle is opened up quite a bit/and or quickly opened......
Tried hitting the tables mentioned above by multiplying by 1.3 and then again by 1.5...... Still stumbling.
