proper forced induction afr????
well got the heads back on the motor today and the lm-1 working.Made a few pulls today with the lm-1 hooked up and heres what i got
cruising around town without boost i get a 14.3-14.8 with light to acceleration(good)decel i go like 18.1+(prolly due to the to atmmospher bov on the maf system)under meduim accel with boost(7-9psi) im running 12.5-13.0(problem????)
and at wot im readin 10.9-11.5
now at wot should i shoot for the 10.5 mark or is 11.5 safe enough of an afr
im boosting to 19psi
if need be i can upload my lm-1 logs so u guys can take a better look

I'd go for the 10.5 to be on the safe side.......always err on the side of caution.

What do you have for a fuel system?
Can you turn up the pressure? Thats a cheap way to "stretch" your injectors.
What size injectors?
Sounds like a cool car 8)

i know they are 24lb injectors, but not sure of what psi they are rated at...and he's on the stock tune as far as I know...just using the fmu as his crutch.
