I was considering installing a BMS Powerbox in my 328i; remaps the throttle and provides 10hp extra.

About 300 bucks.

Even if I don’t, the 328i is still plenty fast.

I’m often surprised on the freeway though when ‘lesser’ cars are handily passing me up.

The left lane on the I-15S going into and through San Diego is 90MPH+ minimum during morning rush.
