2005 excursionv10 how far can one go to tune?

part # u7152 modifying perimitors using predator for a high performance tune... How far can one go to tune??

[mikel]

The tunes we provide are pretty close to fully optimized, there may be a small bit of power left by adding timing/removing fuel from our tunes, but it must be done with a wideband, and the gains will be minimal, on the order of 5-10rwhp if any...

Thanks
