well i had all the vac lines teed off and it was a mess now i cleaned it all up...i actually am running 1 vac line now to the fmu from the top of the 5th gen tb that little nipple behind the throttle plate...and the dyno run i have is just hp a tq no af

 

So what FP are you reading at WOT?

 

I lean up top and I have the vortech FMU and DEK injectors. But I am running the 2.87 pulley with VAFC adding all fuel after the VI opens up but before with teh 3.6 pulley I had to pull fuel because I was hella rich up top. Try with the vortech FMU and try getting a wideband it will save you a motor.

 

as soon as i hit like 5 grand the fp wont go any higher then 60 psi and it starts leaning like crazy...and if u didnt read the posts maxima92 i already mentioned i HAVE a wideband 02..how else would i know i am running lean
