AcidNastyH2, I got the induction towers also. If I were to do it again, I think I would get the filter kit only. Can't say that I think the towers make much difference, and installing them and making them functional involves removing some metal under the right tower with a dremel tool. Lotta work, extra expense, uncertain benefit, IMHO.
As far as weird effects, none so far. Probably what you would end up doing with the tuning is setting it on towing or performance and leaving it there. You could ask the manufacturer if there is some downside to towing in performance mode. Switching back and forth is not supposed to be a problem though.
