Drove up to Atlanta Ga to Vengeance Racing today and WOW is the word. My 2011 6.2 ccsb mods are CAI and a Dynomax 16 in muffler and the custom tune. Before the tune with the mods the truck ran good but after the tune, it runs Awesome. I work for a dealer and I didn't know the trucks are detune that bad. I will post up et before and after tune soon. Long length headers are coming soon.

 

Its quite amazing what a few zeros and ones will do...

 

binary^ for those who don't understand lol

 

Hahah. I was gonna see how long it took for somebody to ask.

It is quite amazing to change a few things and make a big difference.

 

LOL
It really is amazing how much potential these 6.2's have NA. I was amazed how much it woke up with a custom tune.

 

Oh and those 0's are great till you get some of this **** mixed in with it. Got to love getting a tank of **** gas.....

 

it all starts with a tune and it NEVER stops lol and congrats on ur new performance gains

 

Yes, That look like the 2012GTR with a set of to hot of plugs, I help built and a cooler set of plugs really helped. We also mix true e85.

 

Well, I went back to the track to see what the new tune would do. And WOW is the word again but the wow is how slow my truck is. Best run was 14:86 at 94.13 before the tune 14:61 at 96.25 and that was no cool the truck down. Tonight I was cooler the truck down after run. Temp was about the same on both night. But I think the air was a little better the first night on stock tune. But I was hope for a little better time. Well back to my tuner.

 

Went and changed to BR7EF NGK spark plugs today and gaped them at .028 and it seems to be doing a lot better. I had some funky stuff in my tune also (my own doing...to much copy pasting and not taking my time). Haven't done to many WOT pulls yet but they seemed to help clear up the problems I was having.
Talk to the tuner..there should be no reason your truck slows down after a tune.... that just doesn't add up.
