Vortec and cam tunes

[dave w]

Which would be better for cam break in stock tune or the tune Dave W. Posted for vortecs?

The timing tables is a very important parameter. I'm not sure which tune I posted you are referring to, if the posted tune has the stock Vortec timing table from a Vortec black box PCM it will work better than the stock TBI timing table.

Typically the stock Vortec timing table can be improved when tuning.
