From Stock To More Psi

Up to how many psi more from stock can you go without really needing a tune. I know 8psi is stock so i guess from there.

You can go 2# over stock without "needing" a tune, but you will leave performance on the table. A tune will really pick up performance. In my opinion it is a MUST.

There are quite a few people running 4# over on the factory ecu calibration, I would not, but some do.

boost?

I think if you are 99-01 ish years you can go more, it seems that the later years are leaner from the factory.
