Mine has the P1211 syndrome too. Haven't logged the pressure lately because I don't really want to know how bad it is till I can afford to do something about it. My problem is most likely old programming. I'm still running Jody's early E80 from ~2005ish.
So what else could cause low HPOP besides the pump itself? Like leaking injector o-rings or what else could let the pressure bleed off?
My stock 15* pump was running 1300 psi in old 75 hp ts tunes
Then I got a 17* from Mike (rebel chevy) that held between 2800-1900 psi on same tune
Now I'm running a Termy modded 17* and holdong over 3000 psi @ 55% duty cycle on Jody's 80 t
I'm waiting for something else. Maybe an Adrenalin
I would like to see a head to head comparison between Joey's 17* mod and Bob's Adrenaline. Anyone seen such a report yet? The Adrenalines are readily available now right?
My thoughts when I was shopping were that the Termy modded pump was $100 while the adrenaline is $590. I very highly doubt that Bobs pump is 6 times better than Joey's
