HPT is not something we can teach you how to use in a few posts.

get someone who knows how to tune, it's very easy to blow the thing up.

Read a LOT on the HPT forums. It takes MONTHS to learn it on your own, and the education process continues indefinitely.

Check out some other folks' tunes in the forums, and gradually make changes, datalog, make more changes, datalog...etc
