but it looks like I've maxed out the fuel pump

PEAK BOOST:28psi
BOOST AT LAUNCH:12psi
MILES ON THE CAR/ENGINE:57,750/30,000 approxamate(600 passes)
Pulled some timing out with the intent of turning up the boost a bit thanks to a new chip from Eric(thanks again ), first pass was same setup as my 10.51 run from two weeks ago but with 2* of timing taken out went 10.59 @ 127.61. Second pass I added some fuel and put it to 28psi, was on a good run till it started detonating about 800-900ft out, went 6.694 @ 103.36 in the 1/8th and coasted to a 10.77 @ 106. Started putting in more fuel the rest of the day but with little to no change in afr, just enough to make some lean passes at 28psi with the timing turned down. It was consistant though, went 10.504 @ 128.89, 10.524 @ 128.41, and 10.506 @ 128.75. That last one was on a 10.50 dial and had a .007 light
Looks like time to rethink the fuel system a bit for next year
