my trans was shifting late at part trottle,so i adjusted TV cable for better part throttle shifts...at WOT,the motor feels "lazy" (doesnt pull as hard)at high RPM.is my car shifting late?factory tach reads off the scale,scanmaster rpms seem to be at low 5000's but it only updates every 1.5 sec...or maybe the valvesprings?(definitely need replacing) will TV adjustment affect WOT shift points?
