Really? Not what i wanted to hear. So there is no other bolt on add ons from my stand point, its all computer from here? Correct?
Yeah, it's how it is. I'm in the same boat as you. Simply put, to increase horsepower noticeably you need to increase the air delivery as well as the fuel delivery, in one way or another. Your engine is basically a huge air pump, the motion of which is created by combustion.
All of your "power adders" rely, ultimately, on modifying fuel delivery, even if that is in addition to forced induction, nitrous, etc....
With no computer programmability (per se), you can only (slightly) increase one of the two...the ability to breathe (air intake and exhaust).
You might gain a few horses with better exhaust and an CAI, but I think it would be more for looks or sound than anything else. Which is okay if that's what you want.
Any serious power mods you do will probably void your factory warranty, which would include internal engine modifications or swapping out to a '10 computer.
With locked codes, there's no "magic formula".
