I'm still out $50 from dyno proven. I was told he could write me 2 tunes just to try (I had the dp-tuner f6 V2) so I could compare to Jody's tunes, and if I liked I would purchase more. So I paid $50 on top of my order for the dipstick tube piece on the oil pan, received it in a couple days, was told the tunes would be a little longer, after a few times of trying to get in touch and same old sorry, and eventually no answer I gave up. Then i sold the truck, and though I would try to get a credit towards tunes on my 6.0l, never got anywhere with that either, ibwas told different platform, different pricing, whatever. I'll never do business with them again.
