Am getting stroker. Do I need tune/injectors for it?
I spun a bearing,(stock bottom end Evo8) and am getting the AMS stroker kit. Will I now need larger injectors? More air needs more fuel? and will I have to re-dyno the car for the same reasons?? Thanks for the input, and help once again. Mods in signature.

Just to let you know I was in the same situation. After break-in I took it to get tuned and forgot to replace the injectors with the 780cc that I bought. Everyone that I spoke with told me that I didn't need injectors and that the stockers would be fine.
Well, they were wrong! At 18-19psi I was running ~95% IDC on the stock turbo. After swapping in the 780cc I was at 50-60% accros the board.
As for adjusting the tune, the XEDE should be able to scale for larger injectors correct?

There should be no "break-in" for your engine beyond letting it run for 15-30 minutes and doing a few dyno pulls to verify everything is good. It is highly doubtful that the engine will display different operating characteristics after 500 miles as opposed to the above break-in.
