Had mine 5 years ago by a friend who was pretty experienced at it. Cleand up both the intake and exhaust sides (nothing severe)15 to 20hp sounds about right. 13.89@100.25 was my best after the mods below but there is probably another two or three tenths left with a more aggresive launch and power shifting - tried hard not to kaboom the T5.
