Truth or just more BS?

I did some research on what it does and how it does it. It alters the timing, the wastegate causing the turbos to spool up quicker and it boosts the fuel pressure. All of which, despite their claims that it doesnt or wont effect a warranty,..I'm pretty sure should something go wrong and it was discovered that you altered critical events in the motor, they would blast you and void your warranty. Even Pittsburgh Power says it wont effect warranty,.. just unplug it before you send it to the shop. Well duuh,.. LOL

Where would be the best place for this,.. CAT, Freightliner or any good ole boy with a tuner? I have all 3 where I live. And all 3 are hit or miss depending on what you want done,.. LOL.

So what do I tell them,.. "Hey, I need the Hard Cruise setting turned to soft". Just like that?

I wouldnt like it, but I would trade 10-15% power for an honest .5 mpg.

I havent had any tuning done. I had some boost leaks on the CAC couplings, I change my air filter more often now, I upped the air pressure on my trailer tires and have been more attentive to the air pressure on all my tractor tires. I replaced all injectors after 1 went south usually the rest will follow. I replaced all my battery and power cables for the Alt and ECM. I noticed more from that then anything else. I installed a boost gauge and use it to judge how much foot I need, trying to keep out of the boost, or to keep it as low as possible. This helped me retrain myself and is where I picked up most of my fuel economy. I was averaging 4.5 - 5 mpg. Now I rarely go below 5.5 per fill up. Keeping track of it the old fashioned way,.. gallons vs miles.

I'm hesitant to up the power on this motor for now. I'm almost at 1.2 millions miles and other then the turbos which were done at 835k and regular valve train and actuator maintenance, the motor is untouched. It doesnt smoke, other than some electrical issues, mechanically this has been a very reliable truck. So until its ready for either an inframe or new motor, I dont really want to screw with it too much. As the old saying goes,.. if it aint broke,..

Thats what I figured it would do. Make my fuel pig rich and sooty, maybe make it feel snappier giving me the illusion its doing something.

Publicly?

What about in private?

Is it because of Mr Hainey? (Spelling?)

My motor has no emissions, No EGR, No DPF and no DEF. Nada,. After driving 2 other 475 HP C15's with the DPF and regen BS,.. I never want to go through that again. ARD heads burning out, Lower sensor toast. DPF filter needs cleaning, Manual regen required,.. manual regen not working,.. now in limp mode with a full load. 75 mi to closest Pete or Cat center. Putting along and the motor literally shut off on me while going down the road. Will restart, but for only 30 - 45 seconds before it shuts back off.

As much as I love the CAT, I was totally turned off.

Only issue I have now is occasionally I get an Actuator code, but doing an oil change makes it go away. I have had the head gone through and everything has been adjusted and re-adjusted twice in the last year. They gave it a clean bill of health. They said that the oil viscosity can trigger the code.
