whos tunes are you running?

[jared1]

Im running the preloaded street and performance tunes from SCT. I havent made any changes, just hooked it up and running their preloaded setups.

Those codes could have been in there for years!! Clear them and see what if any codes return? The 603 is the cam position sensor. Have you ever had one go out? If so that is the code from when it did. The 0470 code is the exhaust back pressure valve, could just be carbon build up or it could be a bad sensor. I cleaned mine three times before it finally went. Get the part from IH it is much cheaper!!

thanks I will try that with the back pressure sensor. anyone heard anything about these tunes from five star tuning. are they reputable, and are the tunes good. plus I have never had a cam shaft problem

I've never heard of five star tunes. There are a few places I have found that custom tune the livewire, I went with Elite because it was a friend of a friend deal. I can tell you that the pre-loaded tunes are nothing compared to the custom tunes you can get.
