I would, but like I said I already paid for the tune from Inmotion before I even new about the Jerry Tune on Mbworld. Rob has had good results with his tune from inmotion, now I just need to pick up his intake manifolds when they are released. I know a custom dyno tune would probally yield better results in the end, but economically it would not make sense for me to go that route, unless the gains were quite substantial.
