hey guys when i bought my car it was tuned with open headers and a little rich because of nitrous and it was in indiana. now i got the the car in texas and put on a 3 inch y pipe to a bullet and i was cruisin down the street and gave it some gas then it felt like no throttle response at like 5000 rpms. so finally it died on me on the side of the road. at first start up it will idle for a little while then die but you can smell the fuel. would i have to get a new tune because i think its runnin to rich because it s getting choked up on the y pipe. i dont know so help me out guys?
