upgrade will give you an extra 15+ horsepower
This simple ECU upgrade will give your Maxima an extra 15+ horsepower. By reprogramming your ECU, it literally enables your Maxima to use horsepower and torque that was "tuned down" from the factory. JET has been upgrading ECU's for 30+ years and has the expertise to get the most power out of each chip.
Is this for real, it was advertised on custommaxima.com for $349? it must be true if our sponsors are selling it. has any one tryed this? does it work?
