How do you think the 370z is going to stack up vs. the new 1M coupe?

Most people think you can drop a car off at a shop, pay them a few hundred dollars and a couple hours later have a tuned car. This could not be farther from the truth. This might be true on an N/A car where you're retaining the factory ECU and you're simply tweaking fuel and ignition slightly for peak power. With F/I, basically everything you have is out the window. Car manufacturers spend months perfecting the mapping on a dyno. With your own car, you end up with knock in odd places, rich and lean spots, etc.
