I got my truck tuned from Justin at one of his live tuning sessions. I personally would wait for the tune from Justin, but I don't have a truck sitting in the driveway waiting to be tuned.

 

Yeah I did the install myself. Takes a couple days, not too bad working on something that's newer.

 

How often does Justin come to the twin cities ?? I know I was out of town the last time he was here.

 

Not sure maybe 1-2 times a year, just depends on if he gets enough people to commit to a spot to justify him going.

 

Some may hate this since my truck does not have the GMPP crate lsx 376 in it, but here are my new emblems. They are going on the doors where the stock emblems are currently. Soon as I get a day in the 60's I'll get the old ones off, buff it and get the new ones on. They are flat black in color to match the flat black Z71 decals on the rear quarter. Feel free to hate and call em or like em or whatever. If you want the manufacture info on these PM me.

 

Couple quick Revs and a bit of idle with cutout open - 15 sec
Got the tuning closer with Justin, it still starts hard and it has died when I put it into reverse a couple times before engine is all the way up to temp so it is still a work in process. Had a misfire which was the result of a bad plug, but got that solved. So get the engine tuning dialed in and the trans tune as well for the new converter and then it should be done... for now...

 

Finally some videos, all are kinda shakey but u get the point.

That things got some grunt! Sounds great

 

Sounds mean!

I'm curious if using a dyno you could dial in the tune with the VVT any better or can it be pretty much done on the street? I figure with a dyno you can see the changes when advance/retard the cam when on a dyno... kinda thinking out loud here

 

i did that with mine. picked up some power as well.
