06300CSRT8 Did and awesome step by step on building a tune which I have found to be an invaluable tool on my path to getting my tune on point.
I was wondering if anyone had made a similar thread in regards to Nag 1 tuning. Finding it hard to find info on where to start with taking this on. I currently have a tcm that is tuned but I am thinking there are attributes that don't suite my new turbo settup.
