GDP Tuning Limited Support Pack for EZLYNK

I really don’t know where to start . I got this tune package cause I read it was good on forums and online. After going to some shows hitting the track and becoming more informed on the diesel world I learned others have had issues . I have always been one of those guys where if people are hating on you , you’re doing something right . Cause people are jealous . So I just ignored what people said and continued to use them instead of buying brand new ones.
I have a 2017 f250 6.7 with a 4 inch lift aftermarket turbo , fuel injectors and fuel system . And all upgraded delate cooling pipes . I bought truck with 16,000 miles on it . Paid for extended warranty let it get to 25,000 mikes then I tuned and deleted . Order a bully dog tunner with sct engine tunes only . 230 hsp being highest setting I thought that was cool . I loved it but got horrible gas millage and low fuel rail codes . So I upgraded fuel system and turbo . Made even better hsp killing it the track running quarters in 10.4 to 11.3 . Tunes worked great their truck ran amazing . But horrible gas millage like 8.9-9.5 per gl . So I bought a ezlynk and gdp unlimited package . At this time if you tried to get a hold of them on chat they would respond within 24 hours never right away . Which ended up being really bad in Colorado as I sat on the side of the road with know support answers . Now they do not respond to chat at all you have to call and leave a message they call you back the next day does no good if your broke down on the side of the road. The problem that time boost leak I blew a littl sensor that was unplugged out of throttle body . Ok I will say this with gdp tunes for my sotf my gas millage went up to 16-to 18 mpg depending on how I drove . So for fail driving these tunes I thought where way better. Gdp tunes switched at 43,000 miles . At 72,000 miles blew my transmission . I took to a diesel shop they let me know gdp and another company tunes are known for this and they don’t install transmissions . Took to a transmission shop where they rebuild and that’s it said nothing about tunes . There answer to me was tcm tunes where not dialed in wright causing clutch to not shift properly and causing transmission to burn up . Stay away from gdp tunes be ware when I reached out to gdp they tried blaming it on boost leak and assuring me they all use same tunes well they have all replaced there transmissions as well if you look into it. Do not use
