Paccar mx 13 tuning

Factory tuning cannot go any higher. Aftermarket can but not the place to discuss it.
When they first brought the engine to NA and were doing testing on it they had one at 900hp on the dyno for quite a while. Not a legal emission tune however.

 

What issues are you having that 530 is not enough piss in it's pistons? Gearing in the rears or gearbox may be a better way to go. Do you buy it used? The previous owner may had a different use for it.

 

How much are you grossing?

I haul anywhere from 100k to 140k lbs with a 455 18spd.... it gets the job done but terrible on fuel... looking at tuning it but no idea what a good number is and safe

That is an Austrian company, they can tune European MX-13 engines. Those are very different from the US engines. Furthermore, I have not found any tuning company that offers tuning for the present range of MX-13 engines that were introduced mid-2017.

 

Once again why do you think you need more power?
Do you plan on racing up Pikes peak?
If you are heavy haul you have to tall of gears or you need a different engine?

Do you know how to rebuild the engine when it blows apart, or do you have tons of money stashed to buy a new engine?

 

When the MX-13 was introduced by DAF in Europe, the most powerful version had 510 HP. However, they had also developed a dual turbo version that delivered 570 HP. That version was scheduled for a year later, however fuel economy is very important in Europe, and DAF came to the conclusion that their customers would prefer fuel economy over performance, so that engine never went into production. However, DAF has also admitted that the engine as such can deliver quite a bit more then the present 510 HP (US) / 530 HP (EU).

There is a Dutch tuning company that can tune the previous 510 HP Euro VI engine to 616 HP, and increase the torque from 2500Nm to 2804 Nm. They also give a 5 year warranty on the engine. However, so far I have not found a tuner that has anything for the present 530 HP Euro VI engine.
