I notice there are two settings on a Profec B boost controller. One for low boost, and one for high boost.

I have it tuned from Payn Tech on the low boost settings at minimal dial at 5psi.

If I wanted to run the high boost setting, let's just say to run 7-8psi, do I simply just turn on the high boost dial on the profec B, and push the "select" button and it's ALREADY tuned for high boost now since I got it tuned before at 5psi on the low boost mode?

Or do I have to go back on the dyno, and get it tuned individually for high boost mode too to fun the high boost selection?

Did that make sense?

If you have a standalone, you shouldn't have to tune everytime you switch your boost settings....when you get youcar dyno tuned, turn the boost up as high as safely possible for you setup and tune it to that level of boost. If you know you are only going to 7-8psi at the very highest, have it tuned to boost 10psi....That way you can boost any amount of boost safely up to 10psi.

you should be fine with that setting ray.

that little amount of boost change wont make much diffrence from a tuning aspect of it.

yeah, but I want to know that.. since my car is only tuned for low boost of 5psi, will retuning for higer 8psi boost be overall better in response and safer as well. Or if I'm just throwing money away.
