To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience.

Contacted by Chris

Chris with Diesel Ops has contacted me and made arrangements for me to get in contact with someone that will walk me through the process to correct my Check Engine light issue on my 2010 Dodge. Chris was VERY helpful and acted eager to assist me.
Thanks Chris....

Reply from Diesel Ops

Steve,

I am sorry you are having an issue and i am not sure who you spoke to about needing a "Tune" But that is not the case here. I would be happy to get you taken care of and happy to get this problem resolved. I do see however you did not purchase an entire kit so that can be my only guess of what someone meant when stating you may need additional parts. Regardless of what is needed here I look forward to getting this taken care of.

Please feel free to contact me directly I look forward to hearing back from you
