Not sure if I should Post this here but... Need some serious help..
Ok I went to Z1 to get my car dyno tuned.. Mods are Test pipes, F.I. exhaust, Stillen G3 intake. John at Z1 tuned my car on the dyno after about an hour and a half John came back in from the dyno and stated "we have a problem"
he then stated my first pull showed my car made 280 WHP and John could only get me to 304WHP
He stated they Dyno "Osiris" software is showing that I have a knock on one of my knock sensors..
One bank is reading "0" knock the other is reading a knock of 22,800 or so..
John could not tell me witch sensor is showing the knock because my car is not throwing a code.. John stated my car is not knocking, and my motor is fine. According to John he has never seen this before. After a few more hours John looked at the knock sensors and stated they were perfectly fine..
John then went back and forth with UpRev trying different tunes and could not get rid of the problem. They even shut off the knock sensors and it still showed up, John the reflashed back to stock tune and it was still a problem.
Does anyone have any Ideas????????
