Just checking are you running factory injectors?
No I am not

Well then that makes a lot more sense lol. That mod wasn't listed in the first post, but I still should've asked sooner. Give me the part number please.
It?s the white injectors from Grand Prix GXP. 42lb
Stock short block LS1
TEA light ported Trick Flow 220s
64cc chamber (10.5:1)
BTR stage IV cam 233/248 .630/.615 111.5+2.5
92mm intake and throttle body
E85 42lb injectors and Racetronix 255 pump, with hotwire kit.
Kooks 1 7/8 headers 3 inch collectors. 3 inch y pipe to 4 inch Mufflex exhaust Magnaflow muffler.
Th400 reverse manual valve body. With trans brake.
It'd be easier if you would read off the part number.
The GTP had 42lb (@4 bar) white injectors. Are you sure it's the GXP not GTP?
I apologize - 24508208
Thank You for your time !!!!
Here you go. Every change applied up to this point (cranking VE, OL EQ table, SD mode) plus:
Engine>Fuel>General
Engine>Fuel>Transients
Engine>Spark>Advance>Cranking
Idle RPM back up since, after re-reading, you put on an underdrive pulley. Have to keep the voltage up.
Clear fuel trims with VCM Scanner>Diagnostics & Special Controls. Flash the tune. Run it and get a good log of fuel trims.
Copy that - Thank You once again for your help !!!!!

Are you sure that's the tune I uploaded? Looks like it's still trying to idle around 750, and the fuel trims are the same as before.
I believe so - I will try again in the morning - I thought it was struggling to idle as well as rich as usual.
Thanks !!!!
2 logs - 1st one cold start
2nd is cruising
Thank You for your time and patience !!!

Let's see what happens with this:
VE
Idle Spark
Be sure you're resetting fuel trims after flashing a tune. There's LTFT reset, but to the right of it is regular fuel trim reset On/Off.
