Since all the CO people are chiming in......this is something that annoys me, but as previously mentioned, it seems to be a kickdown point issue. If I never let it fall below 50, then I can do the tunnel pass no problem. As soon as I get stuck behind a tractor trailer and the speed/rpms drop, I'm done. Zero power to start from 35-40 and get back up to higher speeds. And that's on a total stocker. If I put bigger tires on, I would really be hurting.
