before my motor blew up it dyno'd at 248whp, and 23xtq on 550/720cc injectors. but it leaned out around 5600rpm. at 8psi.
the previous owner replaced the 720's with 1000cc secondaries, and tuned it, and he said it pulled much harder.
but here's the question.
i bought an rtek 1.7 ecu, and a series 5 turbo. my motor is a large streetported turbo motor, and i know it says the recomended injector setup is 550's/720's.

so if i retain my 1000cc secondaries, and the 550 primaries would i be able to run an safc to tune the injectors, or will i have to ditch the 1.7 and get the 2.1 version?

or if you know of a better setup, please post up.
again, please forgive my ignorance. i live in vegas, and no one really knows about "modified" roataries, and the more technical side of injector setups, and tunes, so its hard for me to learn.
