who uses multistep retard on N/A motors
 

im pretty sure i saw at least one of you runing this..i know the feel of my mustang from when i set the timing upwards of 18 and have that insane down low but looses power up end..as opsosed to the setting it low and loosing the intial grunt but it makes up for it up stairs..with this you can get the best of both worlds..so who is running a setup like this and what er you ET diffrences?
