its already been posted.. A guy on here got peak 6 rwhp and 9 rwtq and thats with stock throttle body, maf and inlet.
by the way, 12rwhp and 19rwtq for 200 bucks on a s/c car with the stock throttle body is pretty good if you ask me. A Bullitt intake will give you more, but for the money, you can't really complain.
