Hi. I am having some minor electrical problems with my car right now, but that hsould be fixed within this week.

I have some questions to see if I am right or wrong. I am currently running the vortech FMU with 440cc injectors and the emanage and profec combo to tune the thing.

I am running extremly rich, so rich the FJO wideband the car has read nothing but 10.0 and 10.3 at every RPM and boost level. The car throws tons of black smoke and I get less that 100 miles from one tank of 91 octane. My FP read 45 when at idle and way more than 100at 16 psi of boost. The car managed to put out 299.6 whp and 29* of torque on a dyno.

Previosly I had the SFMU with no bleed valve and the tuner only know what disk or rink and spring combo. They were still running way to rich so they changed it to the FMU instead (huh?). I firmly believe that I the SFMU is installed back and the right ring/disk/spring combo is installed, the car will run just fine and not as rich as I am right now. With the bleed valve installed this time of course.

The car hesitates to run under low RPM and low boost but it takes off when it reached the 16 psi with no hesitation at all. MY EGTs confuse me too because they will only go as far as 1000F in the autometer gauge at 16 psi and the EGT probe is in the manifold.

I should then run the followig SFMU setup:

2.72 disk and ring with with the black spring
Bleed valve installed and adjusted properly
I should have around 20psi of FP at idle
Around 90 psi of FP at 15-16 psi of boost

Murix. You currently have 550cc injectors right? Do you think I could get a sample of your AFR table from the emanage? I may decide to install those for higher boost preassures.

Thanks for any more info you could provide.

i would say go with the 2.42?? (next smaller then the 2.72) with the corisponding ring. no bleed. dark spring. around 17-18 fp at idle.
