Every penny goes on the Audi!!
Pretty sure it's 3bar, i think a 4bar one people put on as an upgrade. HTH

I asked the question when I got mine remaped at JBS. They said unless you have a big turbo it would be a waste of time.

all promises, no action :)
originally it is a 3 bar. some tuners want you to switch to 4 bar with a remap (like Revo), but most others stay with the 3. BT usually get the 4 bar.

on its own a 4 bar FPR would do nothing for performance.
