Lots of my friends including me get stuff done here.. Chips, downpipes, turbos, whatever. Good enough guys too. Give em a call they should be able to do it, or direct you in the right way..

Edit, Pfaff tuning also has the APR, so probably do a trial, but expect to pay top dollar.. One you go to the site, you will see why..
