Well when i turn the lights on the car runs like crap it wont redline starts sputtering in higher gears at higher Rpm's. not sure how to go threw things see if there grounding out or what. i figure that's what's going on. but it seams like it screwing up the ECU. cause the one that was in it is real back doesn't even run good with lights off but i put a NA in it ran good with lights on or off then later on started acting up doing this stuff with the lights on doesn't run good. Has anyone had something like this on there car any help would be greatly appreciated.

Huh? Can you please clarify your question? It's impossible to understand what you are asking.

But by the sounds of it (and I could be wrong, because I don't understand the question), your alternator is having issues.

with the lights on the car revs slow doesent what to go passed 6,000 rpms with the lights off the car runs fine. i was just wondering what could be causeing this problem. and i hear maybe sometings grounding out when i turn the lights on. but how would i find were its grounding out. on my turbo timer with lights on i still see 13.0 to 13.3 volts with everyything i can think of turning on i see 12.8

Test your BAC valve. Make sure it's getting juice and that the transistor on the ECU isn't blown.
