Heavy Towing With 650HP Cummins Stealth Turbo

Out of the big 3, the Cummins sounds sooooo good. Great information in this video.

Nick is a wealth of knowledge. I’ve valued his thoughts, opinions and products since the LB7 days at Scheid.

You guys are the best around. Love my truck now.

Such a great video an the sounds are music to my ears for sure!!! Another Stella video Nick an Chris awesome information as well.

Awesome video - nice in depth explanation of everything.

Wish you guys and more tuning companies were located out west near the mountains and could do tow testing in those environments. Those egt's you are seeing in this video are nothing. Would love to get your opinion about the data/temps/performance pulling that load up a 2k elevation gain over 6 miles, mountain pass.

Great info

Right on Santos, looking good! Hope to bring my Denali in one day.

Great info guys! When I study your opinions on all of your technical modifications I can't help myself but to think of so many other ways this can be done for every application of driving in terms of size of load, racing, sled pulls ect. I would love to do what you guys are doing, I'm very thankful to see this being done because the factories basically build a single truck in each model. You guys seem to unlock the potential in all of the dynamic components in these trucks. 👍🙏💯. I do have a questions if you wouldn't mind expounding on this topic, my next step on my 2011 LML GMC is air in and air out. My truck is used as a daily driver and I pull a fifth wheel trailer and an extra load of around 4000 lbs so a total of around 14,000 lbs. The truck stock was a strong running truck however I have applied mods and I'm playing the power curve game such as yourselves, I have taken your advice several times and I've realized that I must read between the lines with you guys lol. 2700 bar fuel pressure sensor was recommended by Nick but he did say "don't jump in with 2 feet" and to understand the fuel side of the truck and the immense pressure that is being introduced to

Thanks for the video I really appreciate I was lot information God bless you

My 6.7 has worked it’s ass off since 2007 when I bought it new.

Keep seeing videos on the 64 need a video for the srt 60. Makes me think the 64 is were its at. I talked to the shop for the first time, trying to decide which one to buy.

I know I’m way late. But would a set of compounds help bridge the gap of having high end horsepower without sacrificing the low end torque

I wonder how this turbo compares to an HE451 swap from an ISX engine?

What are the actual differences between fleece cheetah ...BD Screamer...Stealth ..and ATS.. or all theoretically built the same

Stealth 64 vs compound is what I’m debating for my 5.9 since bd started making vgt controllers

Great information, and a great product! What trans is in that truck?

The common rail system, I went with a 2400 bar fuel pressure sensor. My question is about a good combination for a turbo, I'm happy with the stock turbo on this truck however I know that it's time to upgrade and I have listened to you guys talk about the 64 mm stealth, is a 63 mm stealth available? Or would it be beneficial to put a bigger wheel on my stock Turbo? I'm not too impressed with the turbo lag and I seem to have a weak throttle response no matter what I've done. Also another question I have is on my airdog 165 after applying the fuel pressure sensor would it be beneficial for me to crank up the pressure on the air dog?

So is this truck showing it’s numbers with the emissions intact? It doesn’t sound like it. I would like to know where this truck is with egt , drive pressure , and the trans working with factory tuning .

Can you explain exhaust pressure to boost pressure and does that affect egt’s? What is the best setup?
