Hello, I'm fairly new to this forum but I just wanted to let everyone know about my great experience using Marskituning. I purchased my first Porsche, a 2001 996tt earlier this year, and it already had a tune and exhaust on it. It ran great on the high end but turbo lag and low end seemed worse than normal. Mark was very helpful at walking me thru the process and installed a new tune in my ecu which completely changed my performance for the better. The low end lag is gone and the car feels crisp and ready to perform at all stages of rpm. Anyone looking to do a ecu tune should check out Markskituning.com. I am definitely a very satisfied customer

Yes his customer support is second to none.
I recently needed a wastegate actuator rod and he replied to my request immediately and mailed out a replacement asap.
My car has been transformed with the K16 billets, injectors, and tune.
Last month I took my car to VIR and passed everyone in my beginner group, even a newer corvette.
I still get about 25 mpg on cruising on the interstate.

 

hard to beat 24/7 customer service and good product

 

good guy. I also suggest people to buy boost leak tester from 911tuning

 

Thanks for the kind words Michael. Im glad my tune made an Improvement over your existing tune that came with the car.
Best
