This wasn't the fix for me because I had problems with my ECM on my 2009 GMC savana. Newrockies doesn't have a phone number you can call but they do e-mail you back usually within 24 hrs. Jack was helpful in troubleshooting any issue but in the end it was a problem that their module couldn't fix, Justin made sure the refund process went smoothly. So to conclude Newrockies IS NOT A SCAM and I would do business with them again. Scott lipscomb
