With the CAI, the LT's, and the new tune, honestly you should be around 310-320 RWHP which is my best guess(ADJUSTED to sea level ofcourse). I hope the new tune works out better! I may be wrong about those numbers, still kinda new around here but I know for certain with a good intake and tune you should be reasonably around 300... so with the LT's as well you might net more ponies, you might not. It's the luck of the draw. Seen some guys net so little off a good set of LT's and some guys net big gains. Just depends on whats done, and if the stock tubing was really being all that restrictive in relative terms to the overall system.
I am REALLY looking forward to see what happens with the new tune!! Good Luck!
