I was wondering if my 1996 Caprice LT1 with 109,638 miles would be lacking power from the high mileage? I mean me and my buddy tried to chirp up the tires and we couldnt even do that, could it be from the posi traction gripping? he thought it could be my disc brakes or my tranny is weak. It still has the stock 4l60e in it. Let me know what you think.
