I haven't drove the car in the past 2 months on the road. It is parked and it seems the alternator is not fully charging (dash lights dim when i turn the headlamps on). I have done pulley upgrade, intake, and exhaust, and diablosport programmer tune. The car was running great before. Any ideas? The battery did die the other day...possibly i need to reload tune?

I wonder if a new tank of gas would help...unless you added a stabilizer, although I am not sure that's enough time for gasoline to break apart...

the car runs fine when not in boost...surges hit hard in 2nd gear or higher with 50% throttle or more.

Now that i think about it, it is most likey the alternator that is going out. Not enought voltage to supply the needed demand.
