Pretty amazing bolt on numbers through a automatic transmission, transfer case and 14 bolt rear end. Almost a shame your going to put a maggie on there. I'd like to see what it could do with just a cam. I'm a big fan of the VVT 6.2s.

Yeah, I was so tempted to get one of those but I held myself back (extended cab style). There are some great incentives right now. Great Hot Rod truck. 370 rwhp is awesome.

This makes no sense to me. You've spent money on modifynig the truck and then de-tuned it to save 4 dollars or so per fill up? The 6.2L in the Silverado according to GM is factory programmed for 91 octane or higher. Why would you program it for 87 octane? Congrats on a good number with cheap fuel, but why is confusing.

Nice setup! I just bought a 6.2 CCSB 4x4 NHT on Thursday, will be picking up Monday. Any real complaints before your mods? Which transfer case does it have?
