2013 4x4 6.2L 3:73 "E" rated 33" A/Ts.....HyperTech Max running 93 octane and muffler delete with back resonator still on.

002-With Air Filter.

003-Without Air Filter.

Good? Bad? Ugly?

Base line to start building from?

 

Not bad. The AFR could be about a point leaner across the board.

 

How can I get it leaner?

 

Custom ecm calibration

 

Definitely too rich. Get a good tune and it should pick up a good amount of hp/tq

 

If your hypertech is anything like the one I had on my 02 back in the day it pretty much just opens the injectors up wide open under WOT. That probably accounts for the AFR being rich. Like said above ditch the programer and get a good tune from a vendor and you will be much happier. Overall though good numbers for a mostly stock truck.

 

I was in the middle of doing that and was going to start ordering parts for cam swap and then found out that the wife and I are expecting our first.......so building this thang is gonna be slow.

 

Well congrats man ! Maybe if you have a son y'all can build the truck together!

 

Thanks! I'm hoping for a boy but will take whatever the lord gives us.
