Well this all started the day of the dyno but we are not sure. On all of my pulls you can watch the FP drop a few PSI then come back. At first i thought my belt may be slipping. But my tuner thinks it is not because the FP came back. This happens in the upper RPMS. The car is making around 8 PSI but the boost never falls on the gauge. He suspects my FP drop is due to the pumps needing more voltage.
On the street under WOT after about 5k RPMS the battery light on my dash will come on, go off and come on. It flashes a few times maybe once or twice. Now the only thing i can think of is. The belt is slipping and causing the alternator not to prduce enough juice and the light is coming on briefly. Or that there is a big strain for power to both of my fuel pumps. What do you guys think? There is no evidence of wear or anything on the belt either.
