More information plesase.What that foreman tune?Did he Realigned the TPS, Distributor? Do u mean reset the ECU by using the Diagnosys tools? How about your fuel consumption? how about the response when u on the aircond? By right if u get the right tuning (adjustment), U will get the better response.Something wrong with that foreman I guess.
