Tuning
Due to potential accessibility issues with my existing ECU, we started tuning from a stock ECU. Tuning requires VCDS and it is an extremely simple process with the FlashZilla units. I data logged my stock ECU and downloaded the ECU's program onto a FlashZilla unit using the helpful guides provided by Malone Tuning. I sent these files to Malone Tuning via email and within a few days, Mark had a preliminary base tune ready for me. I loaded the tune onto FlashZilla and then flashed my GTI using the FlashZilla. The entire process was very simple and it took less than 15 minutes.
The base tune was already an improvement over Revo Stage 2, but Mark insisted I data log the preliminary tune and send him the results for further tweaking. After two revised tunes, Mark was completely satisfied with how my GTI was performing and I couldn't believe the difference he made.
Results
Power delivery under the finalized tune was significantly smoother than Revo Stage 2, and the linear boost behaviour made my GTI much more enjoyable to drive. Needless to say, my GTI felt much better (and faster) than it ever did before. The best part is that my GTI was consistently pulling no timing whatsoever!
Each time I drive my GTI, I am still amazed that Mark was able to achieve this result. Not only is my GTI performing significantly faster, but it is doing so with much more consistency and safety. Ultimately, Mark's custom tune improved the performance of my GTI while also eliminating all serious risks of detonation.
Recommendation
Custom tune or not, I highly suggest going with a Malone Tuning over any other competitors. Not only is Mark extremely skilled in what he does, but he's also an amazing person to work with. Customer service is excellent as Mark is prompt in responding to any inquiries, and he truly cares about each of his customers and helping them achieve what is best for them.
