We met up with our friend, Stevie, this morning to play around with some Pops/Bangs.
This is a catless setup, on Euro+Drive P1, with Pops & Bangs, 4K RPM Launch Control and rev limit, and catless CEL elimination.
These features can also be used on a catted setup (high flow CAT is recommended). This is a safe, OEM style feature that does not dump any excess fuel or interfere with drivability. This add-on only affects deceleration overrun and idle revving.
