tbi lean..
so after getting my new tbi set up running finally its running lean, when i let off the gas like coming up to a stop and push the clutch in it will die followed by a long crank... after re start it runs ok, meaning i wont die agian until i do the same thing agian. now with the o2 unpluged (open loop) it will not die when pushing in the clutch even at 4k, it will just slowly come back down to idle like it should. but with the o2 unpluged it doesnt run so hot while cruise, here is my set up: toyota 20r engine, gm 2.8l TB, 3 wire heated o2, computer is doing all timming but no knock sensor (cause it would never work right..) fuel pressure is 10psi, please help me with this being lean, its not so fun to drive like this. thanks guys

Have you thought of doing a datalog and check BLM values? Underlying tune may need to be addressed.

i moved map around, from back of the tb to on the intake manifold, still didnt change anything. ill buy a fuel pressure regulator, what pressure are you running?
