Don't worry about the bronze but do worry about your setup.
I have stainless TRSs on my 2005 and love them.
Also have PC III USB.
Also had problems re installing map - being clueless about such things.
Then I got into it !
Do yourself a favour, and do it right.
Even though it is described as an advanced feature, any install of a PC is not complete and right unless the throttle positioner is synched to to the PC. Synch both the Closed and Open throttle positions.The Closed one is the most important. If you don't do, the map will be out of synch with the engine all the time. Then install your map. Why think of 2B ? If the map is as good as their cans, you won't be happy.
I've been using Lord Duck Hunters map based on Moriwakis and it is excellent. Don't be thrown off by the name, the guy did an excellent map and it works great with my TRSs. Got to www.919.org
and you can get to the map. Others to try are the Dan Kyle maps, which are based on early and later Satos. Mr. Kyle needs no introduction. Back to the PC III USB. If you want more help, go to the PC website. Get to Support. Get to Downloads. Get to PC III USB. Start with Tutorial # 10 (how to set throttle position values) Then Tutorial # 3 (how to send a map to the power commander).
Hey, if I was able to figure it out and do it, anybody can !
