too much gas at wot

[apv-stang]

my car under wot cuts out when you shift into second and slam the gas again

i have my fuel pressure set at 38 with the line off

i was also wondering if the fact that i have 24#ers and the fmu is set up for 19s has anything to do with it

if it does what can i do so this stops

thanks

Here's a link that may help ya out.

A 10:1 or a 8:1 (ratio) FMU would be good for 24# injectors...

If your FMU is calibrated for 19# injectors it is more than likely either a 14:1 or a 12:1 ratio which is overkill for 24# injectors which probably is the cause for the car falling on its face.

I would recalibrate it to either a 10:1 or a 8:1 ratio. (change the discs)

BY THE WAY... list your mods and settings (settings = timing, fp "vac off", if you have a btm what is it set at?)

stock motor
24s
75mm mass air
65mm TB
headers
offroad h-pipe
flowmasters
msd 6a
msd blaster coil


10* of timing
fp is 35 with vac off

I am guessing the obvious by saying its the FMU' calibration. I would definately check in to swapping the discs out to calibrate the FMU to 24# injectors.

How do you like the Novi so far?

[apv-stang]

who sells the disks to change it over and how much do they cost

i love my novi-all my friends are dead set on getting them after riding in my car-best 1700 bucks i ever spent

sweeeeeeeet! I am glad you love your novi! I loved mine too!
