[QUOTE="sabotage, post: 13019599, member: 130722"] According to my tuner oem cobra alternators completely stop charging at wot.....it sounds like those huge fuel pumps drain to many amps and the stock 100amp alternator can't keep up. It's a charging system problem check the voltage at the pumps at 4500 and see what it does. Your best bet is the the voltage is dropping ie fuel pressure dropping as well.....and specially if you guys have different lowers with the stock alt pulley. .... [/QUOTE]
