I'm from DE but recently moved to West Deptford, NJ. I also have a new 2017 base with 2,600. I don't know the reputation of any of the tuners but I do know a guy named Dan who rubs his own custom fabrication/tuning shop down in Elkton, MD. I went there once years ago for help with my other WRX and there were a bunch of WRX's there and he seems to be a pro with the Accessport. If and when I tune I will go to him, even for a custom stage 1 for the AP just because I feel like he is genuine and smart and really knows our cars. Other than that, Satoru Speed and Fabrication is the name of his shop. Also, J Tune in Wilmington, DE (Its more like Newport, rt 141 right over the bridge) they seem good. I don't know how close you are to DE. I trust Dan at Satoru in Elkton. I hate driving there BUT he's very knowledgeable. Let me know if you find a good place in Jersey. Where are you at in Jersey?
