I am trying to ballpark what my highest MAF reading will be when running alchy.

Current setup:

Stock Turbo, stock inlet pipe, MAF ~ 1820 @ 7200 rpms and 21 psi.

Future setup:

HFS-5 alchy kit planning to run ~ 26 psi.

I would like to get a ball park idea of how much higher the MAF reading is going to be so that I can rescale my tuning tables now rather than keep rescaling as I slowly up the boost. Anyone have an idea or better yet comparable data?

Thanks
