My friend mentioned he heard this somewhere. The chip out of a motorhome V10 drastically improves the truck V10. I rented a 29' class C motorhome a long time ago, and it pulled my boat up the Grapevine pretty damn fast, I couldn't believe the power. My dually doesn't impress me as much, I wonder if the chip is that much better.

It won't pass smog but you can put the stock chip back in for the smog cert. I did a search but came up empty. I don't know who to contact for more info, any suggestions?

Thanks
