you think you've got time at full boost at over 7000 rpm to be able to fire in 2 banks? depends on your injector flow rate of course, but i don't think you have on 'std' yellows or greens.

why piss about with setting up sequential injection? not really much to be gained imo, and certainly getting the best out of it would be very difficult for a diy tuner without the use of an engine dyno.
