Since We are using maf base tuning, altitude does not really make one bit of difference the ecu will be able to compensate for the changes in altitude wither you are at see level or at 10000 . so the car will still have the same factory driveability at all the time . So far I'm impressed with the 7AT, Nissan has done a good job in programing the TCM . As for not doing any supporting mod to the transmission after going force induction,it is not recommended.. at least you need to install a trans cooler, as we are producing more power the transmission is working harder and it directly effects the fluid temperature Sam Last edited by SAM@GTM; 09-07-2009 at 08:49 PM. |
