e.c.u upgrade

i was wondering if anybody has any idea what company does ecu upgrades for 3000gtvr4 if any. thanks nuzzi....

There isnt all that much an ECU upgrade does to these cars, they were designed with performance in mind. Its not like an ECU upgrade to an econamy(sp?) car.

That being said, dynamic racing (www.dynamicracing.com) does upgrades, but they are based around you already having aftermarket upgrades.

My friend got an ECU upgrade, it was pretty expensive though.
