I want to install my MSD programmable 6AL-2 with a programmed timing curve for boost. I have read where certain tuners will pull the spout set base timing to say 36 for example then retard the timing with a BTM or other timing devise. Has anyone ever dont this??? I plan on buying a fast XFI setup in the near future just wanting to pick up some more power until i finish my dart motor.
