I've got a 2015 m235i xdrive, I have a injen intake, n just ordered a vrsf catless dp, and vrsf chargepipe. Looking at a Mhd tune aswell, was wondering if running stage 2 at 91 gas would be good? Also wondering if y'all knew a estimate of how much whp I'd push… Overall i'm New to tuning and upgrading so any suggestions help! Thanks

Also I am aware getting a intercooler would be better to prevent heatsoak, but I live in colorado and the weather getting colder as we're getting close to winter, I would like to consider getting one next year as winter ends.

I can't answer your question about MHD power as I'm unfamiliar with it.

But remember that Stage 2 without an intercooler has inconsistent power due to timing drops. Sometimes, it will make less power than stage 1.

Colder weather helps, but the engine temps are still really high even when it's cold outside.

Ahh ok, would you suggest stage 1 over stage 2?

Without the Intercooler you're better off going Stg 1. And with those mods, it'll be plenty fun and a great improvement over stock. Not sure for MHD but with BM3 most say it would be around the 380-400hp mark.

Without an intercooler stage 1, the correct decision would be to get an intercooler and call it a day (it will improve the performance on either stage).
