I'm getting a SCT tuner for my truck and was wondering if it would be possible to use it on my wifes car to pull the check engine light codes. My Edge insight will do this for my truck, but it doesn't add power. The SCT tuner will obviously allow me to add power. If I can also use it to pull the codes on my wifes car, it will be easy for me to justify the cost to her. Her car is not a diesel. She has a 2008 Pontiac Torrent (think Pontiac Equinox). She is throwing a CEL currently so if I can use this SCT to check her vehicle too, I can get it much sooner!! I plan on getting it from Innovative Diesel, because of what I have been reading on this site. Thank you for ANY input.
