I think I asked DougF. this a year or two ago but now i can't find my answer. :( I must have erased it.

Im running the Holley commander 950efi with 85pd injectors. I might need to increase my fuel pressure cause my 355 with 144 is reaching its limits on some areas at WOT. I think 21 is standard. what is a safe max to go to? 23-24?

Thanks

raise it 10% and see how it looks.

At about 24-25 or so you bottom the spring out and lose control of the regulation. You'll notice you bottom the spring out.

So be careful.
