The first two things I'd check, is it really 6 PSI, and is it really lean (wideband working correctly).

Lean at 6psi on a stock port and all that injector says there is something very wrong with the car, or the measurements.

Are you sure you have the injector impedance matched?

Seems like a lot of injector for a stock motor, but I'll let some other guys chime in here.

I accidently saw 7 lbs(remember I'm trying to keep it under 5 lbs during break in) and my afr's were 10.9 - 11.5. and I doen't even know what kind of fuel pump that I have, I think it's a Denso.

How much more than my T04e does that BNR stage 4 blow?

no idea but it most likely does flow more considering myne is just a hybrid . so would like to know if the rtek can handle 4x1000cc injectors

I'm told it(2.1) can, you just have to compensate with adjustments. It's not as easy as it sounds if you do a thorough job of it.

dude im sure you'll be good with 750 primaries. maybe even 550's. my buddy was running a T66 precision turbo with cleaned ports on his fd with his stock primaries and 1300 secondaries. so you really dont have to go too big with primaries. especially for a stock port engine.

gsl-se injectors are 680cc. You can use them on the 720 primary settings, but your mixtures will be 6% leaner at idle and under vacuum/low RPM boost. I would suggest 720cc or 750cc to prevent a ton of tuning the vacuum cells. It's not easy to datalog those areas of the map.

720/1000 may be a little short for ~350 whp. Don't increase primary size; increase secondaries to something like 1200c if you're worried about it. That's about the largest injector controllable on an Rtek 2.x.

Dont forget that we don't recommend using injectors more than two "steps" apart.

Thats pushing the utter limits of what rtek can handle, at that range the vaf is maxed out.
