Low fuel psi WOT
2003, 104K, Blue spring (Feb 2012), SRL tune, ~4000 on fuel filters, cruise at 60~64 psi on Auto Meter Sport Comp gauge.
I was rolling into the throttle and noticed a little gauge flutter (mid 50s), then it FELL to 40 psi! Immediately lifted.
On the way home I thought that I would try again, 3/4 throttle, doing good, repeat. Screw this! Standing start, WFO, let's see where it goes. At the top of 5th there was a little flutter. Into 6th it dropped like a turd in a septic tank! Pulled normal, sounded ok, but it fell to damn near 20 psi this time.
Now I SERIOUSLY think it's related, but up until 2 weeks ago the fuel psi was pretty steady, drop into the mid 50s on the loud pedal, then I did some RevX. All of the usual good things happened, but I also noticed fluttering of the gauge sitting in the driveway during spool down.
I'm thinking that the Gillette spring may have to go back in. This is the first time I have ever seen this.
