🤣🤣 It sounds odd I agree, my mate uses the walnut method when doing carbon cleans and he knows what he’s doing around cars, has his own mechanic business and specialises with performance Audis, built his own 820bhp C6 RS6 for starters, although MRC mapped it as the injectors he’s used aren’t very well known for calibration files or something, and they are the only guys that have them, plus their mapping skills are very good as I’m sure your aware.

i wanted to see if MRC used walnut blasting but it seems they do it old school and by hand, or at least used to anyway.

but I came across this thread regarding the hydrogen, and it’s a crock of crap as we assumed 🤣🤣
