between a restrictor plate and throttle bottles with 10mm larger diameters/cross sectional areas. I think comparing the stock TB to a restrictor plate is sort of a harsh comparison. (single large opening compared to a few small holes poked in a large plate). It would only take a few minutes to unbolt and bolt up a set of TBs to do the back to back dyno runs. On the next tuning day up here in Spring, i hope to get this accomplished. thanks.
