GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE

A good reflash will be light years ahead of a lot of the stand alone options out there with in limits. We aren't talking about some of the lame "power programmers" that were available back in the day that offer simple tuning options. We are talking about being able to reprogram all or 90%+ of the factory parameters. In this situation until you are well beyond what the factory sensors (mainly maf/map) can handle in terms of airflow, you will probably be better off with a stock ECU on a reflash.

When the time may come that the mafs just aren't able to meter the much larger volume of air coming into the motor, or you need so much fuel that your injectors are too large to be able to idle well w/ in the stock ecus capability, or similar, then a stand alone is going to be the better option. However to achieve the same level of driveability, plan to spend some time, and some money. The factory ECU can compensate for almost any change in atmospheric conditions, duplicating this ability w/ the tables offered in most stand alone options is where a good tuner with experience will shine.
