here's my problem if anyone can help me out it would be greatly appreciated.
i currently have a to4e 50 trim setup with all the supporting mods needed to run this kind of setup. i have everythinmg from AFPR to VP O2 housing, pocketlogger, greddy evo w/no cat, 1g swap,etc. my question is why am i running extremely rich with 550's on a 50 trim turbo. i fugure that with a turbo of this size, i would need bigger injectors, but thats not the case for me. i have the old style afc which is maxed out to -30 from 3500 to 7200 rpm and im stilling running rich to t he point i'll fall of the dyno A/F ration chart. i recently dynoed my car at dyno works and the results were dissapointing. with this type of setup i should have broken into the mid 300's easily. the guy who tuned my car to its max potential even vouched for me on that. he currently has a galant running consistent 11's and i have a better setup than he does, he said. but here's what my dyno looked like:
RPM HP TQ A/F Ratio
3.0 95 160 13.2
3.5 130 190 13.2
4.0 200 260 11.9
4.5 230 270 11.5
5.0 250 260 11.5
5.5 263 250 11.0
6.0 261 230 10.5
6.5 250 200 10.0
7.0 230 180 off the chart 9.5
my peak horsepower was at 5750 rpm at 266.4 hp
torque peaked at 4250 rpm at 276.3 ft. lbs
this was weaaaaaaaaaaakkkkkkkk. i dynoed running 20lbs of boost as well, but my joe p. couldn't hold the boost well enough because it would spike about 2 lbs. from where i set it. i want to know how come im not maxing out my 550's yet on such a large setup. i was planning on buying another new style afc or just picking up a gm maft. i need to find some way to lean my mixture out other than with my afpr because i still need a pressurized spray to atomize properly. By the way i also have -6 lines from the fuel pump to the fuel rail ( vfaq fuel line mod). I need some help on which route to go before i waste or invest my money into another fuel controller.

could any of this be because of a pentiometer for the barometric pressure sensor or maf issue?
no leaks at all . . . .
