Terrific numbers for Mustang Dyno Bud ! On a Dynonometer my car picked up the typical 22rwhp after adding American Racing headers. Your boost psi should drop closer to 16.5 with the headers as well. If this is mostly a sunny weekend driver you can hook that HP with a pair of MT ET Streets out back. Not sure what rear gears you're running but you can find your traction staging sweet spots especially for 2nd gear rolls .
