[Im walnut blasting valves on n54 and n55 in central wi!]

Are you still doing Walnut Blasting. I would be in the West Bend area but don't know quite when I want to do it yet. Just wanted to make sure you could still do it if given a respectable notice. Car is a 2010 e90 335i xdrive with about 49,000 miles.

Also just installed Dinan Stage 1 tune... Yeah yeah I don't need to hear how expensive it is and not worth it. I want to go stage 2 but need oil cooler. My car did not come with one. Is this something you could also do and is there one you could recommend? Thanks
