Therefore, the difference in altitude will have very little effect on performance. I guess you could argue that a marginal gain might be had by retuning the PCIII but it would not be worth the cost to all but the most serious riders.

HTH,

It is a piggy back, but the PCIII if you have used one takes out or adds "parts" of fuel to a greater range than the ECU and that doesn't move in teh PCIII. I don't think it Add or subtracts it on top of what the ECU is adding or subtracting if that makes any sense.

Maybe contact Dynojet and ask them directly because I understand exactly what you mean, but am probably explaining it poorly.
