[QUOTE=RickyB;168039]This bit of misinformation was most likely started to sell ROM tunes.

The myth goes on. I think the resurrection of the techtom has perpetuated the notion of the locked maps being available. I think it all started back in '97 with the SCCA project. Most people, unlike yourself, not knowing a whole lot about the inner workings of the stock ECU. It's one hell of a shame someone can't come up with a user programmable version of the ECU.
How much work has been done on the AFM..it appears to be logrithmic in operation, as in 75% of it's range appears to be directed towards the lower end of the scale, where it has higher resolution, tapering off to nothing around that 230whp level you mention. Has any attempt been made to re-engineer the variable resistance to a linear output, that you are aware of, to extend the useable range?
