Hell yeah I'm loving it! Got it going your way for sure. How do you like the headers and fit? Any issues whatsoever? Don't know why I agonize so much about doing headers I just don't want any issues because I basically live in it all summer lol.

​​​​​​​I believe You can use carrier out of the 9.5 14 bolt but have to use a adapter yoke to match up with pinion seal. You would have to give Bryan @ Got Torque a call. He just put Auburn pro limited-slip in mine.

Just noticed you have a stock airbox with a custom intake tube.

Have you seen the blackbear test results on the stock intakes?

MIT tube + factory airbox made almost no power and the full MIT kit made about 22whp on a stock 6.2. It seems like these factory airboxes are pretty restrictive. AFE made 25whp.

I don't pay attention when it comes to blackbear. No disrespect to anyone who's tuned or listens to them. They are on my **** list.

Now real world track testing same day. My 5.3 ran 9.35 stock. The AFE that I have on my 2016 6.2 Denali which I swapped over made or run 9.31 at best. Swapped to a AirAid Jr and drop in same thing 9.31 9.30. Then tuned 9.0 stock everything then 8.97 with AFE then 8.88 with the AirAid Jr. Lowest I ran was a 8.61 with E85, AirAid Jr.
Now that I'm running the MSD intake the AirAid won't fit and we had to make our own tube using the stock air box. It's almost a 12sec truck as is.

FOr the money TSP headers are really nice and fit was very good also. I spent over $2,500 on my Stainless works headers and exhaust for my wife's Denali these are as good IMO.

That is sweet. I am thinking about making that swap as well.
