I was thrilled when I actually found the probable cause of all the headaches we've had. My son is still skeptical this will solve things because we had problems long before we swapped heads. I still think that the original ECU was the culprit at first and the new ECU hasn't had a chance to perform because the valve lash problem has been here when we installed it.
I'd read too many positive things about the FAST setup to want to give up on it. I'm eager to see how things progress from this point on.
