like monte said small changes are needed to remain competitive.sometimes these small changes affect a car a different way.even something as small as clutches being made from a different batch of material can cause them to lose the handle.as someone said earlier, I would like to see them keep jim yates .he is one of the most knowledgeable clutch men around a pro stock car.that aspect of the tune up is just as important as shock or suspension settings.most of us have a hard time getting things to repeat once we screw with them and take a while to get it back.these guys don't have that luxury of time and need to test and test.good luck to whomever flies the mopar banner and I am rooting them on
