[QUOTE="04Mach1Blurr, post: 14159414, member: 92273"] Update* So I had a buddy take my car to his shop today to do some more investigating. Went again with the stock alternator pulley on the new OEM alternator and made sure it was on there well. The car drove and idled in the 13s. And at WOT it went as low as 12.7 which is better, but not great. I also found out that from the battery to the ECM, the car is dropping about .3/.4 volts. I also believe that my kill switch i was using as a power distribution block was having an effect of not being completely in line and allowing full current. So my buddy just cut a piece of metal and made a temporary power distribution block and that is also what helped. Main take away* Car is loosing volts from the battery to the ECM. What is the fix? Is it simply upgrading the power wire? [/QUOTE]
