Run what you got! You can always turn up the boost for more power.

17is good, that heads and cam setup is probably about as good as you could get on a 6.0 for mpg.

 

I have a belief if I got rid of this ticking exhaust and bad knock sensor I would be at 18

 

Get to it! I have a Vband leak that developed this morning on my new exhaust. I'm hoping it just needs tightening because its right under the driver side, so annoying

 

Hopefully this weekend I can knock some **** out. Might pull my wheels off and begin sanding them down and polishing them back up as well as knocking the center caps into them.

What brand headers are you running pacesetters or speed engineering? I can get the pacesetters at 10% off but not sure if they are any good, might purchase them next month or whenever they come back in stock at Summit.

 

Ling Long Goi edition headers on both trucks (AKA eBay china junk). Sometimes they take a little hammer massaging but they are cheap, fit, and haven't rusted. One set I bought from LLP 5 or 6 years ago had a Stainless Works badge on them but it fell off before I got them installed and for the $249 or whatever I paid I really doubt they were from stainless work, plus they didn't fit worth a **** on the driver side.

I'd still buy eBay headers again it's so cheap I couldn't justify the cost of Kooks or American Racing.

 

Yeah that is the only thing keeping me away from China crap is I will probably have a stroke trying to get them to fit.

 

TSP headers are a great fit on my Tahoe

 

TSP headers are too expensive imo. Their y-pipe is cheaper than pacesetter though lol

 

eBay and Hammer are the cheapest and once you get past the first whack its easy going.

 

I got the cheapest I could find on fleabay and they fit like a charm lol
