Well I finally got my car back an decided to go for a drive. When getting on it my lights go dim an a battery light kinda flashes an I just let off it was almost like it cut the power a lil..triangle speed dyno tuned the car an I also have a sct with three tunes from Jon lund I just I.stalled one of em an drove it a lil an believe it or not it pulls a lil harder..iam about to go do some more runs I gotta figure out what the deal is the alternator was just replaced,its got a optima battery idk how old it is tho...what do yall think ??
