yep...especially since there isn't a "stock" computer that has the correct fuel/timing parameters for a ls/vtec.

1. crank up and idle, while it's warming up bleed the cooling system. idle for 20-30 min.
2. pop the throttle a few times after it's warm to help seat the rings. not really nec.
3. change oil.
4. tune.
