After some long discussions with Paul at Liberty, I sent my 600 to them. It was a brand new unit never run, so magnifluxing was not necessary. For you guys who have thrashed the box, you may want to consider the small cost of magging as insurance. Any way face plating was not an option for street use and just want the box to shift smoother and better at higher rpm since the ls7 can rev a bit. Heres what you can expect to spend if you send them your box, got mine back mid October.
