I've got a 330ci with stock exhaust, superchip and sprint throttle. I want to know if the characteristics of the throttle is common or just my car. Anyway lets say i am cruising at 10% throttle @ 3k rev and I increase the throttle to about 15%. I notice that instead of the rev increasing from 3k rev, but it actually decreases about 500revs. (btw, % of throttle is not accurate) Also, i was in KL and balancing the car for a short while without pressing the the brake but with the throttle. After that, I experience that the car will jerk whenever i press the throttle to accelerate. Its asthough the car got problems with fueling. Too rich or lean. I need to drive a bit, than only the car will improve slowly. The jerk is like a sudden cut in the fuel, like a fuel cut or ignition cut feeling. Very scary. Finally is the acceleration. I find that my car got problems thinking which gear to change to. I realize that for a 3litre, the car is quite underpowerd. I need to press quite a significant amount of the car to either change gear, especially at around 80km/h. Is this because of the superchip or the sprint throttle that confuses the ecu. Sorry for the long winded-ness. Just very curious and afraid its a problem than needs to be rectified. Thanks. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" /></p></blockquote><p></p>
