I bought my TDI ECU and DSG tune through GDM. Les walked me through the steps for the remote tune of the DSG. I was impressed with how easy it was having never done a remote tune before. The ECU had to be sent to GDM for the tune but the turn around time was [...]

Had my MK7 golf tuned and downpipe installed. Top notch work and great customer service. Had an issue with the tune file but being the great shop they are, they got me in straight away and cleared up the issue. Car runs amazing now and i am very happy with the outcome. Thx GDM.

I got the DPF and ERG delete for my 13 golf tdi. After some time I decided to get a single mass flywheel clutch and Les talked me into the 170 turbo as well. I was nervous at 1st but I love my car so much now. Plenty of power everywhere and I can still [...]

I just wanted to share my experience working with Les and his team on my 2000 Jetta TDI. I think they did a great job diagnosing and fixing my problem (basically sluggish acceleration and an inability to cross 3000 rpm) After running tests on the timing and the MAF, they checked the EGR and intake [...]

Bought my 2012 Jetta brand new and Les and his awesome crew have worked wonders on it since I've had it. Car has had two different Malone tunes, and currently running a stage 3.5 tune with the cr170 turbo. Everything they've done with my car has been done quickly and professionally and I recommend anybody [...]

Being from the Baltimore area there are plenty of VW shops around town for both maintenance and performance work however none did work specifically on diesel or TDI Volkswagens. My recently purchased MK3 1.9 TDI was in need of both performance boost and my leaky pump sealed up again so my search for a knowledgeable [...]

Les is hands down the best Tdi guy on the east coast. I sent him my 2006 golf Tdi for some performance up grades. Vnt 17 turbo, new stage 2 cam, alh intake, full exhaust, stage 4 tune, and a bunch of other odds and ends. This man knows his tdi's! My car is night [...]

Andrew asked me to post my results from installing his 1.5 tune with DPF delete. I installed the GDM down pipe and deleted the cat/flapper/resonator as well. Andrew (for Malones) and Les (GDM) both worked with me to get what I needed for the car and helped with cost, I am a disabled Veteran from [...]

Just wanted to say how pleased I am with Les at German Diesel Motorwerks and Malone tuning. I recently got a Malone stage 2 ECU tune, DSG tune, GDM downpipe and racepipe. I also got a resonator in the midpipe which terminates into the “cat-back” portion of the stock exhaust. I am very happy with [...]

I recently moved from a Stage II to a Stage III on my TDI MK6 JSW DSG. The CR170 turbo is basically a drop in turbo. The flash was a little challenging because my supporting mods are different. To make a long story short the TDI pulls very hard to redline. It’s now much more [...]
