if, as i hypothesized and clark reinforced, the perceived power difference is due to dwell being different/longer, it should be realized that this puts more "stress" on the coil packs.

early on utec users experienced a lot of coil pack failures. dwell was also raised as a suspect. txs claimed dwell was "identical to oem ecu." there was never a definite (ie, oscilloscope) proof that was indeed the case, or NOT the case. oddly enough coil pack failures seem to be much less prevalent these days. perhaps it was fixed in a firmware revision?

nonetheless increased dwell WILL cause more power dissipation in the coil packs and WILL cause them to run hotter, POSSIBLY causing premature failure. something to keep in mind while standing in the free lunch line.
