I have no experience with a tq, but I cant complain about my 6pack, it just runs good. I have used a performer rpm airgap with a carter avs- I wasn't too impressed, then I went to the sixpack on a Weiand/mopar crossram- it ran a hell of a lot better, but didn't really pull below 3k. Then I swapped to a factory sixpack manifold, low end came back strong, but it did lose a bit up top.
