New to the forum . I have just replaced my old 144 blower with a t.b.s .192 blower . Now I have lost rpm with autoshift points . used to shift @6000 with the 144 now with the 192 it shifts @4800 . If i shift it manually it will go well past 6k. no ather changes were made , same timming , same jetting,etc .. have a tci street fighter 700r4. called tci thay dont know just want to sell me moore parts. call t.b.s. thay can't answer me . so my real question is why would a mechanical govener chang w.o.t. shift points? are the lower shift points telling me that im making less power now ? or more ? I did lose 1lb of boost went from 6 down to 5 and the engine runs soooo much smooooother now curse_sign.gif

Up date on shift points . I installed a 3.35 upper pullie ,boost is now a tad under 6 lbs and instaled a quickfuel 950 carb. problem solved . i got to say it now comes alive and shifts past 6k now

Good I was gonna ask how much your boost changed, but you figured it out already.
