Keep us posted , def interested in seeing if ti was slightly weak pumps or the change to the -an size line that helped if it helps.

 

SMALL UPDATE:

Didn't have time to retune the car this past weekend, hope to get time this weekend, however it definitely richened up the car with the new pumps and hose installed... I have been making adjustments daily to get the AFRs at spool up and peak boost dialed in to my liking... One thing to note when taking the old pumps out of the car the sock on the primary pump was distorted and twisted a bit, so I adjusted the fuel sock location on the new pumps.

 

Update... tuned the car on a local Mustang dyno this past weekend and I no longer seem to be having the issue of leaning out. After about 9 or 10 pulls on the dyno to get the AFR dialed in and tweak the timing a bit it holds pretty steady...

 

So do you think it was the socks?
