BM3
Hi guys, I just needed to ask... am I able to run stage 2 with bm3 running on a catless downpipe with an FMIC? When flashing your car on the BM3 site, when running on 93 octane and stage 3 it says that the mods required are an FMIC and high flow downpipes. Would a catless downpipe affect the car with this stage tune?

Without an intercooler stage 2 maps will result in heat soak and loss of power
I recommend you upgrade your intercooler

Yes I will upgrade to fmic but wondering if stage 2 of bm3 is fine with a catless downpipe instead of a catted..
