I love when a customer sends a video like this! It not only sounds great coming into boost but the TCM calibration does exactly what it was intended to do. It keeps the truck in its power range above 3K RPM even from a coasting start. If your tuner cannot post results like this from a truck over 1,000 miles away, tuned remotely, maybe he’s not your guy for big setups. S400 compounds, S&S 200’s and 14mm CP3 on a stock motor L5P in Alberta Canada. I asked him to be sure it was all working together nicely before he beat on it. I’d say he’s safe to enjoy this truck. No reason to build it unless you can use it &s200s

Weekend is here so more trucks on dynos putting down solid numbers. Someone asked the other day about which s400 to make 4 digits. This VS Racing 76mm just made 1077 HP with no spray. Paired with S&S 150’s and a 14mm S&S CP3, it makes a solid pull

2025 L5P. Completely stock internal 10L100, DHD valve body, our latest TCM calibration, Exergy 200’s and 12mm CP3, Stealth 67mm drop in. What I love about the 10L is how dynamic it is regarding bringing the shift points back in line. This poor stock transmission is not capable of catching the lower lower gear changes when they are desired but it doesn’t do anything stupid. It just does the best it can and by highway speeds the shifts are happening when they should. The 9-10 isn’t great but it may get better with some time. That’s not a shift it sees at full power all the time since it only happens if you go past 100 mph.

Exergy Performance released the L5P 300’s so the guys that are planning to do big things with the L5P now have all the injector to do so 💪 Hit us up for yours. We have been working closely with Exergy for many years and have these injectors in the shop truck, Marvin. This truck currently holds the highest dyno number for an L5P making 1413 HP on fuel and of 1579 HP with nitrous. Those numbers are on Exergy 200’s and these are even better!! We have these injectors dialed 👌

Guys ask why our stock fuel and air tunes don’t smoke the way others do. There’s no reason for that. We make clean power and a lot of it. The beta TCM calibrations are bringing positive feedback so they’ll be available for updates soon. New E42 TCM tune orders will all get the beta files. They are stable. It takes a lot of hard work (and money) to keep finding the next limiting factor. That’s why are tunes are worth what we are charging. We’ll work through this issue and let’s see if the highest HP 10L1000 truck won’t be an E42 truck 😉

Might as well drop some LML dyno videos from time to time. We actively tune high HP LML trucks and really love how well that platform performs. This is a big single, big fuel truck putting down 972 HP and 1600 ft lbs out an s472 at Atlantic City

We had several guys running on the dyno at the Atlantic City truck meet this weekend. The guys all made a strong showing. Cody is one of our favorites, laying down 756HP on the Blessed Performance dyno with his stock fuel E42 truck running our favorite drop in, the Stealth 67 Mach 2. That’s a clean run!! It’s going to become more difficult for our competitors to convince people that our dyno numbers are inaccurate if our customers keep showing up to these events and laying the power down on every dyno in the country. Before you drop your hard earned money on the latest Facebook bargain tuning, do your homework. AITP is not the latest fad or social media craze. We are improving our product daily and the customers are the real winners

Getting back to work on this truck has been a blast! Our Global B TCM calibrations work great but having this truck to test for the higher power applications is absolutely opening my eyes to improvements that are possible for every application. I am looking for a few current AITP E42 tuning customers to send beta TCM files to. We need guys that are running our 200hp files daily and already have our TCM calibration to test. Built or stock transmission does not matter. I have beta files I want to test in both. Comment in reply to this post or shoot me an email in response to your order email and I’ll send over something that I believe you guys will love globalbt93

Neal took the Powerstroke on a mission to Arizona early this morning. We apologize for any inconvenience his absence at the shop today creates but the shop phone will not be monitored today. He can respond to text messages when he’s not driving but he’ll be driving almost all day. He is traveling with his family and his kids were excited for the road trip. Please pray for travel blessings. God willing he’ll be back in the office to get things caught up on Monday. We’ll share details of this project as they develop. All we will say is L5P/48 on a light chassis and it’s not Neal’s truck.

Now that UCC is over and we are getting caught back up, we are looking back to the E42 platform. The only thing holding us back right now is the 10L transmission. We are working with Tyler from Dirty Ho**er Diesel. We are at the start of testing. This transmission has about 30 miles since install, all of which has been stop and go, learning the shifts. This isn’t terribly much power yet but it’s definitely showing potential. It feels so good to be back in a newer Duramax with big fuel and compounds, even on a little bitty tune ha. We’ll keep moving forward and increasing power as it learns
