260 possible fuel Problem ?

[STVBOY]

I have a 260 EFI with an A62 digital box. I know the box stock requires 39 psi. Now I don't know for sure but it could have been reworked. If reworked could it now need 59 psi of fuel. The motor runs fine up to about 5000rpm and have seen 7000rpm twice but as soon as I give it almost 3/4 throttle or floor it it bogs down like a lack of fuel. If I floor it real quick it will sound like it almost stalls for a second. Any Ideas would help. Thx John

Check your pump connections for corrosion. That was a cause for a similar problem someone had hunted all over for.

I had same problem and i had to work over a month on it to find that it was the ecu. So save your self the time and go right to a new or another ecu. Dave
