Right now my car has the medium spring in there. My friend had my springs for a while, so I couldn't get a chance to tune it before I blew my transmission. I got the springs back, so once my trans is done, I'll play with them. I did run it without any spring, and it actually ran better then the medium spring. So I'm gonna try one of the really light springs next.
No spring, and no bog/ hesitation? Thats strange! When you tune that, yore supposed to use lighter and lighter springs. Until the one that gives a bog/ hesitation! And then use the one you last took out, the one just a tiny bit harder Youre sure you dont have a vacuum leak there anywhere? Lars
