ye, i meant higher hp than tq, my fault

Ya nice torque numbers.. Your graph is very flat which is really nice..
But i would add some more fuel right where your peak hp and tq is.. I usually aim at 11:5.1 all the way across..
But i like my cars very safe.. Incase something goes wrong.

make sure you connect the bleeder style mbc between the compressor outlet nipple and actuator nipple. if you connect it between a manifold nipple and actuator it'll be a vac leak. the more you open it the more you boost...start w/ it closed all the way and keep trying it a little more open at a time until you get to the boost you want.

LOL! I know how it works :P Do you think I have too much timing up top Sctty?

i was running that original bin that you got at .5*/lb and it seemed ok, but i never dyno'd on that bin. however, i looked at the duty cycle and they were almost maxed. as you add timing it'll get leaner and you'll need to retune the afr. when i altered that bin and went to .75/lb it was much richer and i had to lean it out, which is what i wanted to do to lessen the duty cycle of the injectors. i've been too lazy to install my walbro, so i am still running a stock fp.

i ran as much as 27.75* at 11psi on that one map and it seemed fine...next time i hit the dyno i'll have both chips handy to see if there is any bump in hp and if i can hear any detonation. i never heard any before i was running it.

biggest thing is you want to tune afr at a conservative amount of retard then bump up the timing and retune afr each time and see where the hp is. once you stop making more power, if you don't have detonation, egt ok, and duty cycle is ok...then you should be ok.
