BMW 1M Dual-Mass Flywheel & Tuning
I realised that 1M has a DMFW which is tuned to specific engine load.
Since I'm planning to install a cold air intake and a full exhaust system (downpipe to mufflers), I'm afraid the Flywheel wouldn't take the increased load and the torque curve.
Does any one have a car with DMFW and have tuned it and have no issues?
Second, I know intake & mufflers wouldn't void the warranty if it weren't proven to the cause an issue, but would installing aftermarket downpipes void the warranty?
