WOT Fuel Inconsistency

Unread post by Brewster »

1990 Fox 306, Deka 60's @ 55psi, Pro M maf, Vortech S trim.

Just wondering what I can do about the WOT fueling being a little all over the place, would it help to lower the Imaf points and give it more resolution in 25-50 imaf increments up top since I'm not using the upper half of the MAF much past 700imaf

recently my wot fuel was erratic and I replaced the pump and now it's back to normal. How old is the pump?

I don't think its very old TBH. Seems to maintain good fuel pressure to on WOT, I'll confirm again with a pull as its strapped down atm.
