Default I dyno'd my truck today! 2011 6.2L

Took my truck to PTuning in Manassass Virginia for my first ever dyno experience this morning. Overall, I am fairly satisfied with where my truck is at considering it is all bolt on power so far. First, heres the skinny on my truck:

2011 6.2L crew cab Silverado 4x4. I had to do the pulls in RWD mode. Power mods include K&N intake, OBX LT headers, Gibson catback and Blackbear tune.

Heres how my best pull turned out:



The guys that work there say their dyno is about 12% lower than a dynojet dyno, so they figure I would be closer to 385, not to mention drivetrain loss.

So now the next mod question: Cam or torque converter? Supercharger coming eventually too so please pick one of my 2 options for now. Thanks.

those 24's ate up some good #'s too!

How much do you wanna spend? lol Converters aren't cheap for the 6spds!

Figure out which VVT cam you want and buy the converter to match it. I think the converter would be the more expensive of the two!

Nice! Looking forward to seeing the progress of your truck. I will be selling my motorcycle in a few weeks and will have a good chunk of change in my pocket that I am trying to decide how I want to spend it. Still not sure what direction I want to go

Good numbers, truck sounds awesome. just out of curiosity, which obx headers did you use? specifically a part# and how was the fitment?

I don't really have a budget in mind currently, but I do know that I want to continue modding. Whatever I decide to do next, ill just save up and get it done!

These are the headers I got: OBX LONG TUBE SS304 HEADER 07+ GMC 1500 SERIES 6.2L ALL | eBay

Overall, fitment is good but some of the joints where 2 pieces of the header come together leak. I got 2 of the joints welded. You also have to get 2 plugs to plug 02 bungs. Certainly no complaints about them considering how cheap they are compared to brands like american racing!
