my car still boged at vacuum, it seems like if I am running at around 45mph, 4th gear, at 3000-3500 rpm, it would bog. I was only steadily/lightly holding the throttle...vacuum is usually at 12mmHG, and I can either depress the throttle a little bit more, the vaccum would rise up to almost 0 and then it would run normal....

or I just let off the throttle....and it would be normal...

I can usually tolerate it, I have been tolerating it for sometimes now....
is it the FMU ? I am running 12:1 with stock injectors and airtex inline...
Art told me about the TOO on drilling the stock FPR to relief some fuel pressure, will this help ?

anyway, I am gonna see if I can swap out FMU and see if it persist again..

TIA

you should not drill out the fpr with stock injectors. do u have an in car fuel pressure gauge? your Vortech FMU may be sticking when you fall into vacuum...

thanks Joe, that's what I was thinking, this is the second FMU I have in the car, the first one sticks at idle, I was getting a misfires code left and right at idle...

Dont you just love the FMU?

 

no kidding...the only reason I am tolereating it, is becausa hondata is just around the corner....
