Hi Meat
I don't think that this is a dual post, and after all people like me like to give you advices.
If your only concern is RWHP you might want to check out emission/ feasability with the following items:
Underdrive pulleys: is good for about 12 RWHP (should not be an emission issue)
Cold Air Intake: always helps a lot instead of the restricted c%$#! (Emissions: probabely no, but I am not sure)
Intake Plenum: IMHO a little disapointing 5 HP (not sure about Emissions either)
Diablo Sport Reflash: prooven 15 RWHP (requires 93 octane, allthough other CA people mentionned that it also works with your 91 octane. There is also an option to retard timing and run on 87 octane. "custom tuning"
Other than that I think that you can also temporarly remove the "hydrocarbon crap" in the air intake.
Those are some of the Bolt-ons that a lot of the people do.
How ever I heared that one of the biggest improvements can be made by a numerically higher gear in the rear axle.
(I do a lot of Highway driving, thats why I personally like the original Gear. Cruisin' @ 80 MPH and only seeing 2200 RPM's on the tach)
Check out the following link. That might be something for you:
