Take a look at the Holley Bosch style injector. I use the 105 lb/hr and I am using 35% at 1k horsepower. They are very drivable. Also I run .020 gap for my MSD LS truck style coils. Otherwise it blows out the spark and misfires.
Good to know on the gap, when I order the new plugs here soon, will gap them to that, think they come at .030. I was thinking of going smaller on the injectors but just kept the bigger size, just the old style I have can't be ran at low pulse widths which could have been the issue MadDart had on the dyno when he had the car still.
