Post the tune. Youll wanna go back to a stock or 1bar SD enhanced setup OS since youre not FI anymore. Keep the injector data from current tune and basically start over from there. To change from a 2 or 3 bar OS youll have to revert back to stock OS anyways. From there you can either keep it stock and tune it for the current setup or you can change to a 1 bar SD enhanced OS and move youre stock VE table and anything else needed to the new file. Again, KEEP THE INJECTOR DATA YOU CURRENTLY HAVE to be input into the new file. If youre keeping the 80lb injectors and theyve got the correct data, youll need that data for ANY file those injectors are being used. As far as doing it yourself, we help people daily on this forum to understand and tune their own setups. Its how most of us started doing this anyways. So, its really whether you WANT to tune it or pay someone else to do it again...and again.....and again.....

most importantly though, POST the TUNE.
