2017-2026 L5P DIY Kits. Comes with everything you need. I have set this up to save you money where I can and give the best parts and tuning available. For the guys that need extra help there will be an option for you to select and get 24/7 support. This saves those that just want the tuning and parts even more money.

17-18 trucks will require an unlock cable +$200 (partial refund when returned).

If you are just interested in better tuning than the “In House Crap” you currently have DM me.

Tune files and revisions will be available same day in most cases Mon-Fri. Correct OS and VIN matching on all tuning. Not some half ass hacked BS. I am not a tuner! I am working exclusively with Speed Farm Garage who I feel is the best L5P tuner in the game and these guys have the best customer service and support available. That’s why I picked them to team up with.

Be Good, Do Good, Follow Christ! 😉

In my opinion these trucks are too big and heavy for a 2.0 shock. If you are in the market for an upgrade on your Duramax I highly recommend you check out the FOX 2.5 HTO’s.

I hate header wrap. Especially the cheap crap that comes with down pipes. Not to mention the lame ass hose clamps that after a while loosen up and allow the wrap to separate. After talking with Matt Paul Foster (All Valley Powder Coating) I wanted to try a few with ZyCoat coating. These are finished in brushed bronze which I think will look killer under the hood. They can also do black but, “I like Gold”! If you get that reference it’s cause you old as hell. If you are interested in one hit me up. I’m also trying out some new EGR kits that maybe I’ll pair with these and do some package deals for you L5P guys that want the best under your hood. I’m always trying to do things better and give my clients the best, the status quo is never good enough.

Be good, do good, follow Christ! Later.

Yes, the Global B unlock wait sucks. However, these trucks are amazing once they are unrestricted and tuned properly. Another Denali Ultimate getting the All In Truck Performance treatment. ECM/TCM were shipped UPS Next Day Air yesterday and have landed safely at HP Tuners. They will also return Next Day Air. This is all we can do to speed up the process but it could be the difference between 10 days and 3 weeks.

If you’ve been considering getting your L5P dialed in give me a shout. Let’s turn your pickup into a 🚀.

Be good, do good, follow Christ. Later.

Thanks to Aaron Wiebe and All In Truck Performance for getting this truck tuned while the TDN network was having problems so that I could deliver it to the customer and swap it out for another Global B Denali. That new AITP ECM and TCM tuning is wicked. These Global B trucks are absolute animals when done right! God Bless America and Happy 250!!! You guys be safe this weekend! 🇺🇸🇺🇸🇺🇸

Shop Truck is sitting a little higher than it was before. I put the overload and second leaf spring back in so l could do some uphill tow testing on the water to air intercooler. We’re over 100 degrees cooler than what Ford says is an acceptable charge air intake temp on there 6.7 Powerstroke water/air setup. I’ll take that everyday.

Truck is currently sitting on a 2” drop shackle with Method 803 20x10 -18 offset and Toyo Proxes STIII 305/50R20 tires. It does clear but just barely. More suspension modifications are coming but testing and R&D come first. Off to All In Truck Performance later this week to get dyno results and look at the tune up.

L5P Water/Air kit is Patent Pending and will be released early fall.
