Tunes

I got me a sxt x4 tunner for my 2017 f 250 and I bought some custom tunes from ssi performance. That was a big mistake little did i know he doesn't guarantee his tunes so don't try to get you money back from him any way I loaded up a performance tunes that was supposed to give me better mpg. than the ones preloaded on my xr4 I went on a 80 mile trip and got 15 mpg so I reset it to street which was preloaded went on the same 80 mile trip and got 19 it work answer your emails or if you leave voice mail which I've left 4 time he never called back just stay away from him he talks a good game but can't deliver
