KenP are You suggesting uninstall tuner and reinstall or having programer reprogramed. I made a mistake in earlier post I do have cold air intake, had a huge brain fart. I forgot but I watched more closely this last time and it is redlining and then a little more in that gear only. No other gear go up that high on tach before shift so that gear has to be set back. I have not looked at the Proflash as You pick setting it says to stay with high perf. in all selection even though You can choose different options. If I could stay in High perf. on engine tune and chose a different setting for Trans. I may be able to solve it that way. But instructs say no. What has been your experience if You have run ProFlash which is now the Fast Flash Handheld.
Thanks Ken and partsguy
