Anyway if something came about that I could use I would probably do it.

Is that like a facial cream? Can I buy it at WalMart?
Of course I would get it but I think we would first want to see what sort of gains one could get with bolt-on's and kpro. Most of us dont have a wad like Kenny to get a Super Charger installed on an AUTOMATIC.

I would do it, beyond a doubt. For now I gotta find a few days to get my ecu over to them for the reflash 
but i would jump on a k-pro if available.
I'm putting so many miles on my car and I like it so much I'm thinking it may be around for far longer than I initially planned, and it would be worth it for the long run, re-tuning as I try new parts and all.

The Kpro would allow us to have more FI options, internal builds, etc. If you're looking for just bolt-ons and optimizing the stock internals, a Kpro isn't really needed.

This is from Hondata's research using the TODA race header:
With the lower back pressure and better tuned lengths of the Toda Header, we also needed more cam advance. Advancing the intake cam allows for pressure waves from the exhaust to travel into the intake. At the right RPM range this can assist the movement of the intake charge into the cylinder.
Air travels into and out of an engine not smoothly, but in pulses. Think of blowing across the top of a beer (or wine) bottle. You will hear a note cause by the vibration of a column of air inside the bottle. An intake is the same. For a given diameter and length of tube, there is a resonance frequency. Where this matches the RPM of the engine, you will find a torque hump and lean spot. When we switched to an Injen cold air intake we found the resonance point to be around 4500-4700 rpm.
These dyno runs tested the following:
- Injen Cold Air intake
- Toda Race headers with test pipe (no cat)
- 45 degree VTC cam advance
- RBC intake manifold
- Hondata Heatshield gasket
At this point we switched the engine management to K-Pro with an adapter harness. The two reasons for doing this were speed and flexibility. Programming the TSX ECU is slow, allowing for only dyno 2 runs per hour. The second reason is that we wanted to move the cam past 20 degrees and up to 45 degrees advance.

Note the dramatic differences between the reflashed ECU and the Kpro using the LT header.

It's not optimized for each individual setup.
On the other hand, if you were building the internals (cams, springs, valves, pistons, etc) theres no question that a programmable ECU would be needed.
