Has anyone had a bad regulator, ruptured hose, pinhole, or anything like that occur in these cars? Or what are the symptoms of a bad pump? We ran out of fuel on the dyno at 3300rpm's last night, or approximately 330whp! Combo is the following:
On3 twin 60's
Stock longblock
Off-road X
magnaflow comp axle back
A6
E70
stock pump
JMS BAP at 18.4V
ID1000 injex
ProM Wave meter
spring pressure (7psi)
ProM's data and ID's data was entered prior to the session as a base tune and the car ran absolutely perfect on the road, 2% LTFT's although I didn't get into boost without an onboard WB.
On the dyno the car got into boost and went to the .80 like commanded right away but jumped to about 14.2 on the dynos wideband by 3300. Tuner added fuel several different ways to no avail.
It sucks you can't monitor rail pressure, that would help diagnose this. The pump sounded like ass, sounded like it was pushing more bubbly air than fuel. The shop had 2 other Coyote cars in the shop with stock pumps that sounded identical to one another but completely different than mine.
Lets keep this on subject as the tuner's done dozens of FI Coyote's without issue. Just by looking at the corrugated piping in the tank I don't like the idea of running the stock setup. By spring it was to get a return style system but it may be looking like it's coming a bit sooner. If it is a stock pump/hose issue I could warranty it but it may not be worth the time if it'd be coming out by spring anyway. Just trying to see if anyone has had pump or line issues.
