Hey, I just registered on this site after just recently buying a completely stock 2007 6.0 powerstroke. Truck only has 60,000 miles and headgasket has no issues. I have a superchips 1855 tuner and wanted to know if the low tow tune would be a safe option in regards to the trans and head gasket. I'm not looking for crazy power increase just a little extra over stock. Thanks for any input!
