if so whats the a/f on the street... dynos lie sometimes

anyways you should be richer then that with those injectors and a FPR

turning up static might help some but youll have to end up taking more out of the other palces to i am guessing

i have aem uego.. street dont know haven't got on it and look yet.. its more like 4000 rpm start to work its way down to 12.1 on top 6500 rpm.. also thay tuned it with the one that goes in tail pipe..

AEM uego can data log to a laptop i think.. or to itself and then DL to a laptop

if you can do this

go out make a 3rd gear pull 2800-6500

put up a picture of what the A/F looks like

so above 4000 RPM its leaner... 13-1? and working down to 12.1 ?

this is very important stuff

please let us know

Dognutz, why are you running out of fuel considering you got RC 750's and running a return kit w/ absolute manifold pressure of 50 (and 41 at idle).

There's something funky going on man, and it ain't me.

You car should be pee-ing gas, not running lean. You sure your fuel pump ain't borked?

For people using the SAFC and tuning on the street and the dyno (S1).

Make sure you pull at *LEAST* 4% fuel (across the board), or your car will be backfiring MOFO.. (will hit spark cut due to boost).

I agree with Funks on this one. With the return set-up 1:1 some srt's are only running 35psi base and still having to pull out a lot of fuel on top.

50 + 26 (your boost reference at that PSI) = 76 psi fuel pressure = 991 cc/min

i have no clue.. i think its the stage 2 pcm.. if i raise the feul psi with vac of to 55 and bring the feul persure up with vac on to 43 psi what do you think.. well that stop timming for being pulled

Word of advice man, check your fuel pump.. Cuz that fuel pressure is *WAY* UP there.. Especially for the numbers you putting out..

750's at 54 psi (max pressure @ boost) is more than enough to feed 400 WHP (around 835 cc/min).

Hey Mike, see if you can borrow someone elses fuel pressure guage just to make sure yours is reading right. I know it's un-likely to be bad, but it's something you could eliminate pretty easy.
