M7

[DCM]

Hey I have an 05 M7 and on it I have an slp can and high flow intake. I was wondering if I would have to get a control box if I got an rkt head and a speedwerx pipe? Or even if I just got one of them instead of both. And also would I have to change the clutching? Thanks

I think if you get one or the other you should be fine without a controller. But as soon as you do a pipe/head combo its time to get the control box.

I have an RKT head with 14:1 domes and no controller...it rips.
