I told the new owner exactly what APR said to you . He sounded like he knew and comprehended what I said to him. Yet he insisted of romping on the car.I spoke to the APR salesman he said he would even tell you the logs and walk you through step by step. If the individual was to do the tuning on his/her laptop.
Why are you doing this ALL for him ?.. The kid needs to learn about what the fuck is going on.
