Although we got Pumpkin to run the fastest time ever by 3/10's the MSD 2-step was an epic fail.
The first pass out of the box was a 13.00, what the f@#k.
Tried again same thing and Pumpkin just did not sound right by my friends observations. We tried putting the old tune back in, no difference.
So we disconnected the 2-step from the ignition system and Pumpkin instantly went back to a 12.40 car. Put the JRE tune back in and got after it and turned a 12.08.
Some how, some way the MSD 2-step screws with the ignition signal.
I'm thinking that baby is headed to the river.
