Duramax Diesel Exhaust Mods, and Stuff*

Try PPEI for the tunes. They also do a trans tune that makes a big difference. You may want a new down pipe as well and I got a new Y pipe. If you see a picture of the stock Y pipe you will see why. I also drilled and tapped passenger side manifold to install egt sensor for my CTS. I have also replaced my intercooler tubes. Probably not necessary but looks better because everything is powdercoated same color with turbo inlet also. I also did cp3 and Fass lift pump.

The y bridge is spendy, though, lol. And the down pipe is a big pain in the ass, for something that he wants to return to stock.

Justin can't do the delete. I am calling Thoroughbred again tomorrow

Weird... I haven't seen anyone unhappy with Kory Willis tuning...

Also, you need this sticker, lol.

Justin said that I might be able to find a tuner to write the file, and then he could link it all together for my Autocal. I am not sure I understand this, do you have any idea?

Justin can remote unlock your autocal so you can load someone else's tunes through it. That update happened when the 5 vin limit was removed.

It sounds like Justin is either unaware that you can remote unlock, or he's unwilling to. That would be the only two reasons to have him get the tune, and then send it to you.

If he's unwilling, then I will return my autocal and he can refund me the cost of it.

Hmmm, I don't suspect anything sinister, I just wondered what it might mean. I would like to use the Autocal to save some coin, and get a canned tune

I'm just paranoid these days, lol. I asked about remote unlocking for myself, to go with a local tuner for future mods, as a two week wait for me isn't practical, anymore, so just waiting on that response. Hopefully neither of us has to by a new autocal for it.

Though, I am still surprised they wouldn't do delete tuning for you.

Had a good talk with a guy from AFE. I will be getting their full exhaust system in a 4", turbo back.

He gave me the name of a few tuners, too. But I will check that guy out you mentioned, Dennis

You'll be happy with Kory's tuning. PPEI does good work.
