Hey all,

I just want some advice on my car's power, see mods below:

1. Catless DP
2. RK Tunes Stage 2
3. Straight pipe (except one resonator)
4. CTS Turbo Intake

I believe I'm making about 430 to the crank via BMW's sport display (I know it's not accurate, but I'm too broke for a dyno day rn)

Does that sound a little low? I'm pushing 21-22 psi of boost and really don't know if this is where I should be standing.

I don't think BMW sport display is accurate!

With RK tune, you can get 60-100+ WHP 70+ FT/LBS TQ.

I'm not too familiar with the Rk tunes and how it changes the car but from going off the basics (from what i know about B58) for all I know that a stage 2 tune and catless DP you should be pushing like 450 or so but it could be more or less depending on the duel you use.

Time to visit a dyno and run with stock tune and another with rk

He can't afford a dyno run, or two. lol. first thing i did after installing a tune was hit a dyno.


so i'm going to guess, 5 billion hp. 5 billion and 2 if you have m badges. plus 2 more if you have grill inserts.
