MSD Ignition Question
I have a Roush Small block stroker motor with an MSD 6AL ignition with a 6200 rev limiter chip. If I roll into the throttle the motor will rev to the 6200 limiter with no problems. If I go through the gears from a stop light which puts the motor on the limiter while the tires are spinning the motor will only rev to about 4800 rpms and sounds and feels like the limiter is kicking in. As I get Into higher gears and drop the rpms the motor still will only rev to about 4800 where again it feels like the limiter is kicking in.
Anybody have any ideas where to start looking for the problem? Could it be the chip, box etc...?
