They do pretty good on pump gas your injector duty cycle will be lower depending on your turbo you'll have a lot of room if running pump gas. The idle can be a bit tricky but with some time can be dialed in correctly. Start with a global of -69.1 and start with a dead time of 600 and that will get you close to your target, from there you might have to do some adjusting every car is different.
I use to daily the car only reason why I don't now is gas prices and my commute has gotten farther from work, so I take the Honda. I still bring the Galant out to play though.
