Hi, I'm new to efi and looking for a tune for 09 5.3 lmg. I found holden crazy and was woundering if the stock tunes are for stock trucks our if it was what your truck is stock? Please help me! A friend has the scan tool i'm just looking for a tune. He has it on is duramax and knows nothing about tuneing a gas.
