But it is good information Doc and all new to me.  
I'm going to have to find out just what tune the shop put on mine. When I got my cat bypass and the tune for it in Florida  before setting out across country in June 07,  I ran it up to 135 (indicated) in Montana.  Last fall I got it a bit over that while riding to Las Vegas.   I have not run it up since my 10K service with he new 386 tune. I think the Lynnwood, WA shop boned it though and put back a standard tune without noting I had he cat bypass. I am getting a lot of back popping on decel.
