what do you guys think about using the D preditor on a bran new long block. im putting it in soon and im de modding my lightning while i break it in, just wondering if i should go all the way back to factory back up tune with the hand held while i broke it in? im gonna leave the cat back and cold air intake while i break it in, i dont think it will make a difference, just wonderin about the preditor??

 

Why change it? If the tune is good, it will be slightly richer and have more advance than stock. Both those things will let it run cooler. Your best bet it to drive it like you're breaking it in. Everybody has their own way, but the idea is to let all the parts get to know each other without undue strain.

 

The predator blew up your first motor, why subject the new one to it?

 

Why not just buy a boat? You already have a good anchor
