Stage 2 questions
Just wondering about the safety of going stage 2 with my current mods. currently running bm3 stage one on my 330i. The only required mod listed for stage 2 is a catless downpipe, which I installed recently. Any other mods I should look into for the safety of my engine?
Side note, anybody know how much horsepower you can get out of the b48 safely? |

This graphic from Navardi lays it out pretty well.

I’m running stage 2 on BM3 currently. I have VRSF catless DP installed, and as far as I know, you should be alright with just that. I got a chargepipe (FTP) just to be safe. I hear the OEM chargepipe can crack with the higher boost from stage 2. I also have a Dinan CAI but this shouldn’t be needed in terms of stage 2. Haven’t had any problems with my setup so far.
