So I have read on here that going from a smarty to HP tuner you might have problems, well I put the smarty back to stock and then tried to pull my stock file to HP tuner and it won't read. So what's my options? I emailed smarty for a stock file. Will this fix it? Why does smarty claim it won't leave a trace, but it seems like it does. I really don't want to go to the dealer and get it flashed because the smarty messed things up or misrepresented what it does.
