so on a cost per horse power perspective
$50 per hp is pretty good

not takeing torque into consideration

for caparison:

5000 exhaust, say a 20 hp gain
thats $250 per hp

under drive pullies $350
12 hp gain
thats $30 per hp

$1000 software update
14 hp
thats 71 per hp

all numbers are ball park of course, off the top of my head
i always kinda wanted to look more closly at these numbers if there isnt a thred already on it
