Thanks for the info, btw I never had any intention of removing the alda completely, my car is 99.9% original and I have no interest in modifying a car that came off the line during the golden years of Mercedes engineering. It sounds like everything may be working the way it should then? If I floor the pedal from a stop, the car pulls hard from a stop, the only time I notice a lag is with part throttle, if thats they way these cars were from the factory I have no problem with that, I just want it to be correct. If the alda adjustment calls for rich enough to just see smoke on full throttle then it doesn't seem like its adjusted lean, as there is a fair bit of smoke with the pedal floored.
