- 2001 mazda protege mp3
Ok no one will know it has an mp3 ecu so the ulev thing isn't an issue
The only thing that will change cruising rpms is the gears in the trans. Synthetic oil and a tuned ecu will not and can not change that.
Also the start up clatter is lifters, again not something the ecu has control over
Also a cat back and header will reduce back pressure which you need for low end power. That will lose a bit of low end power.
The protege is way under powered there is no "beast" in this car
