Diesel DNA Tuning

I had a great experience with this company. Shipping was pretty fast and customer service is very great and you cannot beat their quality for the price you pay. The parts are a very good quality. Didn’t see very many reviews on here so I figured I would leave one. I would highly recommend this company for any of your tuning and exhaust needs.

Over the years these guys have been very helpful with anything I've brought to them. Always been able to source parts in a quick manor. Anything I haven't wanted to tackle my self they have taken care of me. Honest service at fair prices

Great customer service, answered all my questions in timely manner. Very happy with my purchase

Purchased exhaust and a tune. Took a month to ship it despite being told and day. I wasn't in a rush. So that didn't matter. However, the tune I got was terrible. Took my 30+mpg touareg and made it get less mpg than my 06 duramax crew cab 4x4. Got one revision after twoish months. Update didn't fix much. Finally got back in the low 20s mpg. Slower and worse miles per gallon than stock. Radio silent for the last few months. Bought a Jr tune and now it's back in the 30s and lost .5 off the stock 1/4 mile tune. Would not recommend.I see they commented they would help me out. Just so everyone knows. Never reached out. I cannot stress enough, do not waste your time. You will regret it.

Great service, attention to details, perfect results!!!

Nice down pipe and delete… but the tune never did get right. Multiple emails and new tunes but never did run right after tune☹️had checked by mechanic for vac leaks and turbo but all that was good. Mechanic says would need tune again.**update, commented on there FB page as I never heard back from email then I got blocked ! Buyers beware*

Ordered a deleted kit and tune for a 2010 tdi. Kit fit perfect and I’d consider shipping fast coming from the other side of another country. Had some trouble with the tune not loading to car and these guys didn’t stop until they got it right. Would absolutely recommend them to anyone. Customer service was top notch and their knowledge was as well. Will be using them again if I ever have any diesel needs.

This guy is great! I didn’t realize the difference in time zone and he even answered my call at an unreasonable time. He is very helpful nd took time to help me out and get me setup. Awesome customer service and the parts are great quality.

Terrible. Go find out for yourself.
