i broke mine in shit was easy turned it on for 30 sec made sure shit was good to go then turned it back on let it do a heat cycle
let it cool for a little went for a 10 min drive HIGH vacumm style with my boost gauge in kinda conviennt
no lie shit ran rough at first it needed a valve adjustment but i did that after a week, drove it in high vacum still
week later about 300 miles changed oil shit looked real clean motors run real quite now, valve adjustment went well
its about to hit another oil change im at like 900 miles now gona change it at 1000, ive done some 1st and 2nd gear rips here and there but never WOT on highway or nothin and so far this shit is great no leaks oil looks good
and its good to go
