Anybody receive their custom tunes in the past couple weeks?

Will keep you updated. I don't tow, but have some a few hills to contend with. I checked a few gear ratio / rpm calculators online, and found the 4.56's shouldn't make the engine scream like I thought it would. Try 4lo.com for their calculator, enter your info, and see what you think. I was starting to get paranoid about ordering the 4.56, but feel better about it now. Still need to order master install kits, but will post when they are installed. Hopefully in the next week or two. Later, jumpn
