Hey guys...after putting the Velos tune back on my X5M, I am getting misfires under full load (but boy is she pulling hard!) Code is misfire on cylinder 5 - 002B1A.
I am going to change all the plugs and coils, but wondering if there are any specific plugs I should use to prevent misfires with the tune? Or just use OE Bosch from FCP Euro?
