worked some thing out. it runs sweet, but is still wierd the way it works. i
tried running the exhaust plugs as #1 ie backwards, and its good, normal way
isnt working. does this mean the cam is out 180 or what is going on
still stoked i drove it with boost :)
didnt have any brakes though so i didnt want to get too excited
cheers all
andrew
