msd?

I was at track sunday ran an 8.01 in1/8th. Another mopar racer that was trying to help me get into 7s. Told me to try by passing ballast resistor cause msd dist. had one built in.We tried it disconnected and nothing we made up some jumper wires to by pass it and it sounded a little crisper but still did not not get into 7s. Anyone ever heard of doing this,Kevin.
