I recently purchased a 2009 Nissan GTR and the first thing i did was get a tune from Doug from Weapons Grade Performance. I was very satisfied with the performance that i gained from the tune.He showed me how to operate the features that EcuTek come with like the rolling launch, raised the boost level and also removed the speed governor. Doug is easy to work with, great communicator, has a clean shop and, reasonable pricing. Highly recommended. Trusted source for my GTR work.
