Hyper Tech programmers

I have a 2000 SLS 2dr ,that I am converting into a mini Denali, and I have done almost everything to give it more power. I was wondering if anyone knows if a hyper tech programmer will do much in the way of giving me more power. Ihave went through and saw little gains in hp so is it really worth it.

It will give you some, will also help shift points.... Look into getting a v8 :P
