did you ever have the injectors cleaned and flow tested?

 

im not a fan of dsm injectors, seen many freeze up randomly.

a newer good condition stock fuel pump is easily good for 350 whp. how many miles are on this pump?

i would certainly replace your fuel filter if it hasnt been changed recently.

ALSO I would triple check to make sur eyou have all the wiring correct for the vafc.

Pull your plugs and check how they are, if the dyno wideband is reading correctly, its super lean, and you should not keep doing pulls, if you start to do a pull and it goes lean, LET OFF. you can seriously do damage in a split second. youre lucky it hasnt blown up yet.

be careful and good luck

 

thats another thing i was thinking...they hooked up the wideband onto a vacuum and stuck it in my tailpipe...how accurate is that? I would assume it would read leaner because it is not getting all the exhaust gases...

I'm going to change fuel pump and filter today, but how should i go about seeing if this solves the problem? should i get an egt, would that be accurate enough to show if i'm running too lean? I dont wanna pay another 100 bucks to dyno the car, only to find out it was another problem...
