i just did this got all bran new turbos and everything, now i know my service tech as a friend, if you DO NOT. TAKE OFF YOUR PARTS/TUNE and delete codes return vehicle to stock, BMWNA will flag all vehicles to get diagnostics reports sent to them so they can analyze to see if you have had any aftermarket parts, mostly looking for a tune and revs past stock. JB4 should NOT leave a footprint they can easily find.
