when I spoke to BR about going 20G LT eventually I was told 680's would be ideal for somebody like me that's going to be running pump gas boost levels and they suggested the 780's for race gas boost levels. They warned that the 780's will be difficult to achieve good gas mileage for a daily driver. I'd like to know how these cars with over 680cc injectors are doing on a daily driver with the stock ECU handling them.

I'll be referencing this thread when it comes time to scale my own...good information.
