Ok, i've been searching around over the past couple days and can't seem to find any information on chipping a G35. Most modern cars have an ECU uprgrade good for several horsepower and cost around $600. is anything like that made for the G?

 

Technosquare is one of the only places that I have found that will reflash the ecu, but after reading some posts there might be some issues with them depending on your particular car.
