Hi!

I have a 2016 f10 m5, 32k miles, it has a stage 2 tune by a local reputable tuner. I would like to go down the clutches/chargecoolers/meth route eventually. At the moment I have a slight misfire at high revs (6250 rpm onwards), and I can't seem to find the cause! Car has had new injectors, MAFs, O2's, coils, plugs (oem and 97506's with various gaps).

To cut a long story short, I have purchased a JB4 for when I get meth, but I'd like to fit it now for datalogging purposes. What map do I need to use to be able to datalog, but not interfere with my stage 2 22psi map?

Any help or words of wisdom will me greatly appreciated!

Thankyou!
