Hey I just bought a 2015 BMW 320I XDrive. Ive done some simple maintenance, cosmetic changes, muffler delete, and my oil filter housing gasket.
I was thinking about buying bootmod3 and holdoff on the cats for a bit, will running a tune with cats still perform good? and are there any supporting mods I should install or maintenance before installing the tune? Any advice is helpful. |
