I installed an mst intake today on my 2013 335 f30 n55. I am experiencing very rough idle and sometimes the car even stalls. I checked for vacuum leaks and if my maf sensor was in properly. The people at autozone said I need a tune. what do you guys think is the problem that's causing everything to misfire?

I have the MST and it has none of the issues that plague other intakes. The MST is well designed. You must have done something during the installation to cause an air leak or to disrupt the operation of the MAF sensor. Trace back your installation steps. Here's a video to reference.

Hope this helps!

it looks like my maf sensor wasn't bolted down all the way. could this be the cause of it? also, since the car is misfiring, would I risk damaging the car if I turn on the car now and see if it's fixed?
