Agree. Don't know of many or any other new england gt-r shops. I think Kaizen went out. There's Bren tuning but I thought they mostly did subaru's.When you get a chance I'll take the name of this NE shop to avoid...If/when I decide to mod....Thanks..I dont understand the secret stuff if its factual and keeps other GT-R owners from getting F over, we all need this info...jmho
