Upgrading just the turbos is fine with the current software. The only difference you might see is a tiny bit more lag and slightly lower pre-intercooler intake air temps.

I always wondered what the duty cycle was for the stock injectors on the 2.7T. On my Saabs and Volvos even when I jacked up the intake charge pressure using the stock turbos (19-20psi on the saab, 14psi on the volvo 2.3T) I found better performance with bigger injectors. Also, the saabs and volvos utilized rising rate fuel pressure regulator replacement so that made a difference at WOT.

I suspect if the duty cycle on the 2.7T injectors is less than 100% the stock ones will be ok....as long as the fuel pressure regulator can compensate for the increased manifold pressure as well.

Thanks for the info I actually found a place in new jersey that does milling and theyre sending me K03s milled to k04s so I can keep all my stock hardware
