gm-maft and safcII are a perfect combo.... if you are a CHUMP just kidding

but I have dsmlink (shh...) and gm-maft(shhhh...), and it works wonderfully. What I love about the gm-maft as a blow-through is the fact that it reads the air AFTER everything else, such as pressure drops, boost leaks, and temp changes from going through the FMIC and all the piping. Thats what my goal was. I've been in cars that still had dsmlink with a stock MAS and they are still not as smooth as one with a gm-maft. excellent innovation.
