I wish there was an LED or something else to tell you which mode you were in. It's pretty poor you have to guess that it's working. Installation was easy and directions were straightforward. It works.

Everything was pretty smooth. my truck had a few little issues and they have been more than willing to help me through it. great folks

Steps were clear and easy to follow. Any questions I had I received quick responses from staff. First post emission diesel I've owned and they answered any and all questions about the process. Already recommended 3 other people looking to make their rigs more reliable. Thank you guys for the awesome work.

Had an issue with my switch emailed ca tuning and they had amazing response time helped me figure it all out 10/10 look forward to doing more business in the future
