steve99: it's as you wrote on all accounts of how it works and what provides, what not .. but still, that 'feel good' bit, that some testing it reported. - Yes, it won't bring more power, but seems that those that tried, prefer throttle opening curve with this to that of OEM .. so at very least imho this might be worthwile mod to try to implement with OFT, alongside other existing mods, like cold start, economy mods and such. Just like clutch pedal bite point adjustment or short throw shifters, it may enhance enjoyment of driving and imho worth experimenting with, even if there is no actual performance improvement except subjective feel. But it's fun we are after in these cars, no?
