    I agree, pretty much the same thing for me. I looked in alberta and everything is selling for 5K off MSRP. Didn't make much sense. Hopefully a repair recall announcement comes very soon and replacement with the ISB21.

    it's been a few weeks now since this update. No issues to report, truck runs great and isn't drinking DEF. I did mention earlier about some strange noise at cold start. It happened once and i haven't heard it since.

    I think if I remember right the TSB said the fast feedback program was going until the end of May 2021?. I don't personally expect to hear anything until after that.

    Had it done yesterday. Didn't have any of the issues or problems, figured might as well get the latest while it was in. Few hundred KMS on it so far and no issues. Will report any issues, seems to have alittle more go in the pedal after.

    Industrial Injection CP3 pump and installation and follow on use!

    The ticking noise has gone?. No more spikes in fuel pressure?. Sorry more questions. I've been watching ready to swap in case the "service solution" isn't a replacement pump.

    Thanks for all the updates NordicNevs. I'm assuming I would have issues with a deleted truck and converting. Most likely tuning problems?.

    Here you can freely post your concerns about the CP4 fuel pump - free range just keep it civil.

    I wonder where we can do this in Canada. Doesn't let me fill the form in properly with address etc..
