Whooo-hooo, I'm getting close to maxing-out my 60 lb-ers. Time for dual in-tank pumps, too, to replace my Walbro 255 in-tank and 255 in-line.

 

Shoot support at hptuners.com an email with your serial number if you'd like the fix for that wacky cut off graph

 

Same hear.

 

Of course they are maxing Mike you are at like 39psi fuel pressure...... Is that right? 39?? Is that with the big Pomade stained pump?

 

LMAO.....right, but with two pumps he will be getting twice the flow @ 39psi

 

Yes, 39. I moved the pump you remember down by the tank, it didn't last long. I replaced it with another, it started to sound bad last week, and I replaced it with a Walbro inline. The Walbro is much quieter, but at a rated 255 l/hr, it's just not motivating the fuel enough.

 

Try dropping in an 8.1L fuel pump right in the tank, should fit right in the basket like stock. Mine is doing great up to 65% IDC with the 60's (actual IFR of 72.3 @ 62psi). Just an idea.

At 39psi, you are getting what.......like 56-57lbs p/h out of those injectors? Bump it up to 60psi and you get another 18lbs p/h. That should put you in the 80% IDC range i bet.

 

Yeah, they were about 80% with the other pump.
