Just wanted to let everyone know how great Ray's warp transmission tuning is working on RevMax's upgraded 68RFE. It shifts really smooth the converter locks up in third and pulls strong from there on. Ray's customer service once again is second to none, weekends or holidays he is there for you. i've seen on here other guys waiting for regular business hours to get their issues fixed, this is not the case with Ray. If anybody is trying to make up their mind on a tuner look no further than Ray @Double R Diesel, especially now with his deals. Thanks again Ray for all you do.
