For a mild rebuild for a tune only/lift pump/ max effort tune truck, just curious on some options. I know suncoast makes great kits, a few people around me have ppe stage 5 kits. Wondering what the difference between the ppe stage 4 kit and raybestos gpz kit is in power difference. They both only run 5 c3 clutches, no machined pistons or apply plates in either. Now that the gpz has been out for a while, has it proven to be an OK mild rebuild kit? Or are the old altos in the ppe kit a better option. Just curious. Thanks
