I think I need to sert or have my dealer try one more time, since changing my download from stock I have lost exhaust tone, a couple MPGs, now have an occasional big backfire on decel, I'm loving the power of a stage one upgrade and the bump up of the RPM shut-off. Funny thing is it felt better,sounded better on original map. So is now the time to sert or let them have another tweek? I'm sure they will want more $$$.
Just a heads up, all those SE race tuners have been discontinued with most all of the other power making products by SE, The PCIII is a much better choice being they are always being upgraded and new free maps being offefred.
Make it worth your while! Go with an air kit, exhaust, PCIII/custom dyno tune (by a qualified expert). Money well spent for performance and excellent fuel economy.
