A real person that does tunes will run esn and see what the internal parts are rated for.

 

That was my first electronic motor i had no idea about them but i do now lol

 

and you had YOUR tune done by him...when?

 

There a few people calling themselves the Diesel Doctor...the guy with the shop in Effingham behind the Hardee's is legit. Yes, he may use ESN for a tune, but what do think the internal part difference between a 430hp and a 490hp DDEC III, or 455 vs 515 DD15, or a 400 vs a 500 ISX??? Nothing it's just the software.
Granted if you want a super trucker tune, 6-700hp+, then there are guys out there and those tunes cost $1000.
He did my 14L Detroit, from 490 to about 560ish...this was 6 months ago. The power difference is substantial, about 3/10 increase in mpg, I don't downshift as often, better low end torque..... Before my EGT's would get to about 650, now close to 800...still very acceptable.

 

No one is going to tune my Detroit don't want or need power. Was just asking about the manifold and turbo. Unless it can be turned down to say a 350. Or 380 hp. Have to much power now.

 

A guy I used to run hopper with put a PDI ceramic manifold and a Borg Warner setup on his 6NZ CAT last year. His EGT at full tilt now hovers around 850* when before it was close to 1000*. He said he's seen .3-.4 mpg gain from doing the manifold and turbo together.

 

That's true in some cases and false in others. Always know what power your serial number was assembled for.

A 435 CAT and a 475 CAT have significantly different hard parts for 40 more rated horsepower. And the same is true for other manufacturers.

 

About 3 years ago. He had my injectors timing way off.

 

435s can go to 500. But he pushes them past 500 which is asking for problems.

 

I cant complain. my tune has been spot on for the last year and I will still endorse him and stand by my choice of tuner. sucks your timing was "off", whatcha do to fix it? Michael will turn it back to where ya had it if you bring it back and don't like the tune he put in it.
