My car is completely stock aside from a densecharger cai and 14* timing, without replacing the intakes heads or cam or using a blower what would be the best way to get it to run high 13's. Its an auto btw. I plan to put an offroad pipe, flowmaster american thunder cat back, 3.45's or 3.73's and im not sure what else from there.
you didn't say no spray.
