rob ive been meaning to call you back for 2 days but ive been ill! injector size is ~550/1500 and running on only primes. redline is 8500, anything over really heats up the motor and wears it down..harmonics and all. it makes max power around 6800/7300 and torque comes online pretty heavy after 3200 and climbs to the upper midrange to support the topend power w/ the chopped lim. rob cant wait 2 catch up!
