Excellent info! I will definitely get them to tune if powerchipgroup falls through. I think I will still go with larger injectors if the weak spot is the MAP sensor. This way I can upgrade the MAP sensor and keep the fuel linear. I might try it without, but I'm worried about running too lean when a stock MAP voltage would be (for example, rough figures only) ~ 4.5 v at roughly 20 psi and a 2 bar sensor would display just over ~ 3v then the ECU (thinking the stock MAP sensor is in place) will think a lot less air is moving through and output less fuel through the injectors. However upgraded injectors would get by this. More fuel would still be added due to the larger injectors despite the lower MAP voltage.

Your input has been great, I think I'll have a lot of trial and error on my hands in the next month or so. I'm pretty confident I can get it working though, since I have much control over my MAP sensor voltage outputs with this Apexi tuner. I really think 2 bar MAP sensor and upgraded injectors will do the trick.
