Been tuning a GM crate LS3 with a mild TSP cam (225/330/114LSA)
and 1-7/8" long tubes. It has the card style LS3 MAF in a 4" tube.
Speartech made the harness. My transmission is a built 4L65E. My
issue is with the returning to idle. When I drop the gas too quickly,
the
engine will drop to 400RPM and nearly die before recovering. Been
struggling with this for about 6 months trying different things and
nothing really helps keep it from dropping so far down rpm wise. I
did the EQ/VE tuning and got it perfectly dialed in with a wideband.
Same with the MAF tuning...its great and the MAF is screened with
a honeycomb and has a nice smooth response curve. Car runs great
all around except it tries to die out when you release gas too quickly
in or out of gear. I tried adjusting the throttle follower torque by
looking at other sample tunes to no avail. I try to resolve issues on
my own and have come a long way but this one is testing me.
I will try to attach my tune.
Thanks.
