The Nissan Path

Does anyone know of a good performance chip or tuner for the 2001 Pathfinder SE? I'm looking for better mpg mostly, but would love a tow haul mode for power too.

I think your options are going to be pretty limited. You might try UpRev as they specialize in Nissan ECM tuning, but I'm not sure if they go back that far.

Thanks for the tip, but your right, UpRev stops at 2003
