Has anyone tuned vtec killers? I am curious if u would start with a ls basemap and just start tuning from there? Any opnions or tips on doin so?

 

vtec killer cams are easiest to tune since there is no two fuel and two timing maps.

As more lift they have, you need to add more timing to compensate for the loss of dynamic compression ratio. Don't be afraid if you need to add 5 or more degrees on idle.

 

Thanks for the reply I am thinking of goin this route
