voltage drop under load? when the car is at idle the voltage gat is somewhere between 13.9 and 14.2 but when i jump on it the guage slowly drops down to about 12.9 and i start getting knock retard. My question is is this voltage drop normal. I do have a e-water pump and some n20 goodies if that helps.

Well the only thing that might be causing that is the fact that you have the LTCC coil packs , i am no expert but i would think those would draw a little more power under load. also with the electric water pump too, so i'd say 12.9 is fine under load. **** mine is like 11 something at idle cause i have UD pullies and under load it goes up to like 13.5 to 14.
