hi my name is gary and i live in sarnia ont. canada.i have a 2008 mustang 4.0l v6 with a v3 si trim and a custom air to air intercooler and a custom aluminum intake manifold i made.the car has so far run a best of 13.26 at 104mph at st.thomas dragway this fall.i am having lots of issues with surging and have gotten a better bov and am converting it to a blow through system with hpx maf.also it ran the 13.26 without a proper tune on the dyno .i just modified the factory diablo tune that came with the vortech.i have a sct aswell and when i get the custom tune i wil use it. it really laid down on the top end and started bucking around.i know it will run in the 12's cause my buddy ran 12.82 with the same kind of car and vortech.looking forward to next year.anybody else having trouble with the plastic diverter valve?
