proper forced induction afr????

[project89]

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.

well im pretty sure im out of injector.so im stuck the way it is now.have to wait till this weekend to convert to speed density setup and see what happens.though even with the afr were it is it hasent had any detonation.

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.

yeah im gonna swap to larger injectors and look into running dual walboro 255 pumps right now im running a single 255 walboro 55 base fp with 85 psi max. ive got to do something cause im itching to spray the 35 shot on this motor

just thought of something would my methanol injection be messing with the afr's? im spraying pure methanol, comes in around 9psi
