I just got the car a few months ago and as far as I can tell the only modification that's been done is previous owner had it lowered with h&r race springs.
I am going to get an aftermarket charge pipe for sure... I had so many problems with the pos plastic oem charge pipe on my 335 it was ridiculous!

With just a stage 2, it's highly recommended you change the intercooler and the downpipe and therefore the charge pipe as well.
How do you plan on safely running an aggressive tune such as stage 3 but still keeping the car mostly stock? Sounds like a bad idea. |
Well besides my charge pipe having to be replaced twice on my 335i I had no issues with just a tune
