Man im telling you, Eric with IDP is who you need to get in contact with. Its not the handheld tuner, its your tuner personnel.Well the tune isn't fixed. I am so ready to just get my money back. I don't know if i am just having bad luck with it or if all these problems are normal at first. My Looney tune smokes so bad when the truck is cold it's rediculous. All i can use right now is my street tune and it's really nothing more than a canned tune. This "wonderful SCT" is just a big pain in the a**. I am either gonna sell it or find another tuner!!!
