Basically. So much faster... like seriously keeps pulling. So much more torque... some reason i feel like the pop pops got louder.
Highly recommended.

My C43 gets better mileage with the RaceChip Ultimate ... _when_ I'm driving it gently (i.e., as compared to when I'm driving it the same gentle way with the RaceChip disabled). The "funny" thing is that setting the RaceChip to its Eco setting does not give me better mileage, whereas setting it to Race does (within that comparative "gentle driving" caveat). I suspect the reason for this is, at least by viewing the boost gauge, it appears that the RaceChip runs a small amount of boost at 1100-1500 RPM, whereas there's normally no boost at that range under low-throttle conditions.
Of course, if you drive it hard, more HP/torque = more fuel consumed, given that it's the same engine (and yes, it is true that there's more temptation to all that extra performance). It's about discipline! ;-)
