Need someone to look over my log (HPT) 2002 Ls1
243 heads
LS6 intake
Stock MAP sensor
medium sized cam (242/249 590/590 112)
SD tune
Just got the setup back together and everything seems good except for initial startup. Engine stutters and wants to die, then runs fine. My main concern is the MAP sensor showing 7-12 psi on the log. I am unsure if this is a normal thing with an SD tune, or if i made a mistake when wiring the harness Please let me know if you have questions. Any help is much appreciated

i'd offer more help but i cant see the log because i refuse to "upgrade" from hpt 2.24.
if you have the same injectors from before it would not surprise me if some are plugged up from sitting. make sure youre running on all 8 even if it sounds right once it warms up. mine was down much less time than yours and i had 5 dead injectors when i put it back together.
cant help you with the map reading, 7-12 psi (or even kpa for that matter) makes no sense SD or not

I had the injectors cleaned and flow tested.
