MSD 2 step with FAST XFI

mike britt · 12-26-2022, 10:42 PM

Is the Efi going to have a conflict with the engine being on the 2 step without an input from the trigger? Will I need to lean it out at the rpm it will be on the 2 step? Need a little help understanding how that works.

I run stock eliminator. I am like you. I thought I might need to change the tune up while I was on the 2 step. I decided to try it and see what happened. It ran just fine. I didn’t have to change anything. I was leaving at 2500. Don’t know about anything higher because I can’t run a trans brake. Don’t know if this helps but that’s my 2 cents. Good luck.

Mine is a stocker too. I just put it in and tried it in the shop and it popped once like fuel in the header or something. I can hold mine with the foot brake to 3000 but the 2 step with a 3000 chip it creeps. I got an adjustable chip so I can lower it a little. Don't need any red lights from creeping.
