Holley Projection

Has anybody here used one of these? I installed one on my 350 a few weeks ago. I ran the return back to the tank. Used a separate temp sending unit, separate from the radiator. Fuel pump is located right at the gas tank.

Am trying to get it dialed in now. I was getting 7.5 mpg! Hell, I went with this to improve gas mileage and do away with cold starts. It really works well. I just can't get good mileage yet.

I tried trimming the "main" back to lean it out. That seemed to make it worse. So now I am trimming the "accel" adjustment and think I may be improving it.

I understand that I'm never going to get great mileage. And I'd be happy with between 12-15 MPG.

Anybody have any tips? I have a friend who owns a hot rod shop here in Austin who says he's installed a bunch of them and doesn't think it's a bad unit. I'd rather not take it to him unless I have to. $100.00 an hour is well worth his work. I just like to do what I can by myself.

Thanks!
