pz7252 0 Report post Posted May 28, 2014 Hi guys, has anyone out there done this swap. I’ve currently got a m52tub25 and looking to upgrade to m54b30. I’ve herd it’s a straight swap and all you would need to do is flash the DME for a b30. But I want to use the b30 manifold as the airflow is much greater, but the m52tu has a drive by cable and the b30 has a drive by wire. Will it work to use the adopter plate for b30 manifold to m52tu throttle body to run the m52tu MAF. Quote Share this post Link to post Share on other sites
