if the haltech wasnt a 1912 version E6 i might consider keeping it, but it needs an upgrade. MS isnt a new idea lots of 8v NA, 8v turbo, 16v na, and 16v turbo guys have beening using it since the MS1 came out. now VR6 guys are dabbling with it, as well as 1.8t swap people.
just got 5 gallons out of it, i guess ill leave the rest in.
