Sent an email for a return label and got a return email that said they don't except returns on parts that had been installed. I'm out $500+ for a tuner that does not work... Will never order from them again. Be careful about ordering from them.

took my $ and never shipped my item. took my $ and never shipped my item. 3 months later I have emailed them 4x called and left a vm 4x ZERO REPLY SCAMMERS!!!

On top of getting someone who can camunicat in an engaged sence of interest with the product they are selling. So I fully appreciate being a stranger on the phone and getting good guidance. I only credit the advice after I had installed the kit and found a leavel of trust in diesel ops for them telling me every thing I should anticipate during and after installation. I will definitely be doing more buissnes with them.

not impressed I got the wrong turbo I couldn't tell in the picture but this one is for a later 2004 f350 which has the different pedastool so now I have to get that other one. It's not that I want or need a sinister sticker or diesel ops sticker or shirt or receipt or anything but you figure when you spend 1600$ on a turbo you'd at least get a sticker and a receipt

2012 RAM R2500 This kit made an improved performance with the truck quite obvious. The installation was clearly stated and depicted. My technicians only issue was that there was NO instructions included with the product. He went onto the site and downloaded over 20 pages on the instructions and manual which I provided to the customer. For the cost of the kit,at least the installation guide could have been included. He had to take time to get this from your website,and you know,a technicians time is VALUABLE.
