I know if i had alot of horsepower i'll have to end up changing my driveline right??

 

Trans is the weak link.

 

Weak link is definately trans as previously posted. It's not a power adder but with a solid build you feel more of the "power" you were missing. Also people told me a 5.9 swap. Now that I have im very happy. The rpm's don't need to climb so high to move me around. Night and day difference in TQ output. Just remember air in and air out efficiently.
