I have used GDM for my TDI tuning for the last several years. First up they did a stage 2 Economax tune on my 2012 6M MK6 Golf TDI. They did full race pipe EGR delete with full 3″ exhaust and GTI rear muffler (great exhaust option for super sound but still very liveable inside, must do for any modded MK6 Golf TDI!). Great performance and mpg upgrade, I’ve seen as high as 48 mpg, and even spirited driving resulted in 42 mpg or more.
Then my buddy and I added the CR170 turbo and GDM retuned with 4 bar MAP sensor Economax stage 2 and stage 4 tunes. They also installed a stage 2 South Bend clutch (and later upgraded to a DKM clutch). Still the same mpg on either tune, very little smoke and plenty of power. The support was great as well, any questions were professionally answered and issues resolved.
My most recent project has had them tune and delete my 2014 A7 3.0 TDI. Still great service from Ryan and any questions answered professionally. Once again I did stage 2 and 3 Economax tunes with the EGR delete. Exhaust is downpipe and mid-pipe, with stock rear muffler. Sound is very close to stock inside with a small increase in sound quality outside. Have yet to put on enough miles to report the mpg increase… but power is great! Tons of low end torque!
Thanks to GDM my TDIs run way better than stock on mpgs and power. I recommend checking them out for any TDI support!!
