my car which engine is mitsubishi 4G91
at 90km/h the RPM already 3K
which i think is quite high
is it possible to change my 5th gear to make 3K rpm at 100-110km/h???
because i travel quite alot at high way therefore can help me to save some fuel also
where got forman can do it??
roughly how much will it be??
