Hey Guys : Just got done installing the silber turbo , Start the sled and right away the check engine light comes on and stays on ? Was wondering if anyone else has run into this and what they did to fix it as we can not come up with why its on as everything connection wise seems right. Any help or ideas to look into would be GREAT ! One other side question I had was at idel the AFR guage is reading 22.4 I am in Iowa so way low elevation and I have the control box still set on the stock settings, so was just wondering if this was kinda normal as I hadnt moved anything as we are going to wyoming and thought It would need to be adjusted anyways. Thanks if you want you can call me with any input or write me as I'm new to this stuff. Thanks Danny 319-461-4368
