It included new fuel rails with 80lb injectors and new regulator. The car was tuned and everything is fine on the dyno. The car made 500rwhp. The only problem is when the verhicle is cold the idle is really terrible. It idles at 550-700rpm's. Like it wants to die out. It sounds like the computer si trying to find itself for some reason. Once the car is warm the idle is fine at 950-1,200rpm.We tuned the car with an SCT tuner and the air/fuel is great. Its the idle that we can get figure out. Any suggestions? :thumbsup:</blockquote>
