Stock turbo 1/4 mile ET record 10.640 @129.74
Unlike most of TCU programming on the market, not only do we increase TQ limits and raise the the rpms, but also we are able to shave at least 40% of the shift time between gears by decreasing the time between shifts.
The stock TCU has limits set forth that often take control and shut down the throttle body between shifts at 1.2 bar and above. We strongly recommend this often overlooked upgrade. TCU removal is required and shipping to us for 24 hour turnaround in most cases. With our ecu and tcu programming, our clients have consistently ran below 11 seconds in 1/4 mile.

Just gotta give kudos to Marek Deejay Markski at Markski Tuning for helping me tune my TCU and ECU… such great guy and customer support is unmatched…
the car is so much better slow speed, city driving. WOT, tiwsty roads… wow! Ive tried a lot of tunes in the past this by far one of the best, car is very linear especially combined with the TCU tune… I just need a new exhaust lol! love driving the car…
I must say that Markski tuning TCU tune is THE BEST choice for Tiptronic cars on the market!!! I have tried other vendor TCU tune and it is not even close to Markski tuning. The car is smooth when cruising at slow speed and way, way faster than stock through the rev range especially at WOT. When shifting in manual mode, shifting delay is reduced to almost none. I am enjoying the car so much. Customer support is excellent and Marek answered and discussed all my questions with patience. Thank you Marek!!!

Wow amazing how much of a difference this made!! Woke up the car shifts are lightning fast and completely different. I can’t believe what a simple tcu tune with ecu tune dramatically woke up the car. Car has turbo spool noises that are very apparent now. The linear power is just unbelievable. Highly recommend this to everyone that has 997.1 turbo it will definitely be a MUST HAVE and first upgrade along with ecu tune from markski any one skeptical , I had the Eurocharged beforehand and freaked out on them to get my money back . This TCU tune is genious!! Highly recommended and overlooked upgrade👍
