Keeping it right at 0 or -1 is probably the best as most ecus really start dumping the fuel the second the MAP shows a positive. It's pretty agressive acceleration much more than most n/a's so you can coast a while. With the extra TQ we can shift quite early and not be bothered too much in driveability even with a 4 cylinder. Driving like that in a N/A 4 cylinder especially from the early 90s or earlier would shake it apart, and ping like crazy.
