If you send me the dyno run file (.drf) and I'll show you what they really mean. I can easily make those numbers appear, plus I can make them higher or lower if you want. People just don't understand dynamometer operation and will take anything at face value if marketed to their weakness.

Are you just too lazy to do anything yourself. Just go run some data logs.

I may be wrong and a "tuner" can chime in, but I didn't think it was really possible to add HP/TQ to these trucks without the tune being revised for that part. Basically the truck is programed to make a certain HP/TQ and will make changes to maintain that. Sure you can install something new and put it on a dyno and see a gain momentarily, at least until the truck learns. But that doesn't necessarily mean the new part made more power.

Now that I look closer, I see the scaling for HP and torque is different and they do in fact cross as expected if you replot.

I put these on my 18' soon after buying so as not to have to deal with frozen studs. My opinion as stated in pass threads.....Snake Oil! Maybe I needed to pay more for the higher HP ones!?! Wish they added that kind of HP! Not hating, just no noticeable difference from stock. The HP on that sheet would be noticed! Save your money unless your tuning with other mods.

I put these on when my 2018 was a week old, made a difference in drivability and noticeable reduction in turbo lag...that is all by the seat of the pants, not dyno, meaning a real world difference in driving conditions.

Turbo lag!!!! Such an old term and overused today. Modern advances in twin turbo designs today are light years ahead of old single turbo motors of yesterday. Tuned? What is that old term again? Even stock this engine spools up very well.
