need some input on tune greetings, attached is the start-up/base tune along with a short cruise and 1-2 upshift WOT pull log/scan. i understand the injectors are maxed so my buddy's in process of getting 60lb injectors. here's the rest of the mod list:
70s chevy vega
bored and stroked 408ci that was originally a 364 6.0
stock ls2 intake manifold with massive CAI and cone filter in the fender
cheap headman's long tune headers
compression ratio is 11.1:1
LS1 NA Stage 4 cam from lunati 235/242 with 111 LSA
PRC heads
the wideband was installed in the tailpipe and using LM-2 wideband
TH350 with 3500 stall with 3.73 gears
i realize the lean at the bottom of 2nd gear based on the LM-2 AFR registering +16. i also understand since the widebands in the tail pipe the reading is reading leaner by +0.5 to 1.0ish?
trying to figure how much to adjust in the MAF range

The injector duty cycle is like 113%. I don't care how much fuel you put in the MAF table, it's not going to richen it up.
and bruh...WTF is up with that VE table?
I'd wait till you get the bigger injectors before you hurt this thing.

Since you are logging Commanded EQ ratio, change your WB02 to read in Lambda and use the EQ Err math parameter.
Yes you can do the same thing with AFR, but I find Lambda is easier. Just my .02 on that.

like i stated, i know the injectors are static, we only did one run and stopped there because of that. once the injectors are in i will be redoing both VE and MAF.
