| Fast XFI - LT1 |
Subject: Fast XFI - LT1 by tjpreul on 2015/9/30 1:55:32 Has anyone installed the Fast XFI on an LT1. I bought the system earlier this year, but just now am able to install it. There isn't a good install instruction manual. Fast said to I can remove the factory ECM for a cleaner look. I just want to be sure that I'm not going to have to go back and fix something. |
