Thanks, Mark@tunerworks in Calgary hooked me up with Rims and Springs.
Not too sure on the exact Hp, but I suspect around 340-345hp and almost 400tq to the crank depending on the map There's a guy on the 5 series forum (Jaekeem) who ran some dynos on his 535i and managed to get 290hp/339ft to the wheels with a 15% drivetrain loss thats where I suspect crank numbers will be. Im also guessing that these numbers are at 4.0psi over stock.
Burgertuning also has a Dyno with 2.75psi over stock below
For the most part in the city, I'm just running 2.75psi over stock on 91 octane. However I have ran it a couple of times at 4.0psi over with 91 octane and it's a FUN
machine. When I track it this summer, I plan on doing 4.4PSI over stock with 93 octane
I'm not sure how much it will shave off from 14secs on 1/4mile but I'd love to be min 12.99sec on 1/4 mile. If i can't achieve that... maybe I'll explore Meth and a custom 3.5" downpipe
