I am looking into buying a DVD/ Blue-Ray to learn to tune my Chevrolet LS1 5.7L engine, I bought the HP tuner pro software but feel that I could use a better understanding of how to tune. I know there are different help videos but would like to get some good feedback so I can use your experience to help me make the best choice. Thanks ahead for your replies.
So have any of you bought the Greg Banish GM EFI Tuning DVD and used it? If so when you tuned your car was it with the HP tuner software? Was the DVD helpful in using the HP tuner software?
