well that has nothing to do with the performance of the engine. Its just how the throttle is controlled (and I think it eliminates the TPS).

The main performance differences between the K24A2 and other K24A's is that:
1) the K24A2 has higher compression (10.0:1)
2) the K24A2 has true 3 rocker VTEC on both intake and exhaust.
