Installed raceme ultra with 5"flo pro turbo back exhaust. Install was straight forward, many post and threads on here to walk you trough it. Once programmed started with 120 hp tune was fun went to add transmission tune and truck had a fit dash flashing and truck shut off. Quick text to Ray and found problem raceme had not been updated. No problem took out trans tune and all was good. Only issue was truck seemed too,quick shift. Downloading new file was A little bit of a challenge for a non computer guy. Thankfully wife is handy with computer. File downloaded to sd card and raceme would not recognize it. After a couple unsuccessful tries post a post to the forum and get a helpful hint to unplug obd cable and bam it worked. My recommendation is never flat foot skinny pedal as the transmission does not like it, roll into throttle and hold one truck will set you back in the seat. That is on 120hp tune. And the good news is the lie meter says I've gained two mpg's since yesterday. Thanks to @Double R Diesel and @DanO
