never even bothered without brake boosting, i don't want to see the number lol

my brake boosting is to let go as soon as the revs stop climbing (around 2100rpm), so i didn't even build that much boost, just enough to give it a kick in the ass.

i feel the TC intervening in some runs so could have been faster with DTC but i don't want to be unsafe

Sorry to hear that, what year is your 550?

I just changed my engine air filters to k&n. The engine filters were certainly dirty. Feels a bit more responsive but weather is still too hot to test fairly. I have my new Michelin pilot s4 tires going on the car on Thursday from the oem all season run flats. also trying to find whatever the best intercooler upgrade might be for it. That one's a bit tricky.

is your 5s 0-60 brake boosted or without brake boosting?
