General consensus on boltons to gain the most HP.

No, not at that time. I had FI Catback and FI longtube headers.

My previous Dyno was 295WHP with just stillen intakes and muffler section delete. Then when I went to dyno after installing all the other stuff I did 300WHP. (although my mid-range torque was a lot better) Intakes must have been big, because everyone seems to consistently be around 300 with full bolt-on's on Uprev's shop dynojet (where all my dynos are done).

Back on topic, I think the first thing you do, regardless of what it is will have a substantial impact. I agree with Jordo, you can get 95% of the gains of the expensive stuff and pay 50% or less if you do it right.
