Pinned - No change in mileage over 5 weeks.
Do you have a returnless system? The BAT's lower, injectors, and rail is for a returnless system.
I liked them pinned, but keep in mind I am nowhere's near stock. Plus have 10.25CR and aggressive cams. (I.E. I'm setup for high rpm HP, not the compromises the stock cams/setup is designed for)
