can i go ahead and run 50lb inj w/ 4 bar setup on my t25, or do i need to wait until i bolt on the 3037? what would happen if i get the 4 bar program, but leave my fuel pressure at 3 bar until the new setup goes on?

hmm... running the 4 bar program but only at 3 bar... I'd guess it'd go lean and blow things up. If you run the correct fuel pressure, yeah, you could probably run NA with the 50lbs, 4 bar program.

I'm not NA, I've got a BB DET w/ the stock T25

You can run the 4bar w/t25 no problem.

yeah, I know. just sayin, you could run NA with the 4bar setup if you wanted to. No reason too but you could. I mean, all the ecu does is read the maf voltage and pump in the right about of gas, that's about it (well, more complicated but you know).

if i go ahead and use 50lb/4bar and my TTZ maf, my fuel and air will exceed my turbo efficiency. what's the most i could get out of the T25, around 14psi? Also, would it matter if my ecu had the S4 program, and i ran stock BB cams temporarily, or would it run like crap?

I would think the car would run fine with the s4 prog. and stock cams. Not perfect but not horrible. yeah, past 14 psi is diminishing returns.

car will be fine if you dont have s4's. But if your "really" worried about it ...get S4's...hehehehe
