candid review of bmw performance power kit for n55

i had the bmw performance power kit (software only) installed yesterday and had some time to drive it both city and highway (30+ miles) today.

frankly, i am having a hard time noticing the added hp or tq. i never found the stock engine lacking power but i honestly can't feel what others have felt... such as faster response (still have that dead zone) and reduced or eliminated turbo lag. is 20 some hp and tq too small for my brain to distinguish?

one thing for sure is that it completely changed the exhaust sound (stock). it's is much deeper and louder from 2k+ rpm and the burble is kind of nice.

maybe the soon the arrive catless dp will add some additional power.
