: Turbo issues... still..

Got the car running now... it idles decently... But.. it is falling on it's face in boost. I thought it was running lean.. but inspection of the plugs revealed that it's running a little rich. No sign of detonation anywhere on the plugs. If I partial throttle it.. it runs great.. I am running it with the Tial and 5 psi spring for now. If I floor it.. it feels like something is holding the car back. It's very hesitant to turn over about 6500rpm. I checked my battery today... and at idle.. with lights on... I am getting 11.8-11.9 volts to the fuel pump. I checked directly at the battery... and it's about 12.6 volts. Could it be that the battery is bad.. or altenator.. and it's not getting enough voltage to everything? This could cause a weak spark and it would blow out under boost right? I've changed everything I can think of... even the ECU. I have (2) 4 guage wires grounding the engine out. And a 4 guage from the battery in the trunk.. to the front. Also.. a 4 guage from the battery ground to the chassis. Since I hooked those bigger grounds in.. the car seems to idle better. It doesn't die on me anymore. Anyone wanna comment on the battery theory?
Thanks

when i have the de motor in, it would get to about 5k in the revs and fall on its face. it ended up being a bad distrubitor. replaced it and no problems, until i ran it low on oil. just an idea, good luck
