I have version 1.20 with the horrible surge at 2000 that makes me look like I can't drive..apparently 1.23 gets rid of this? Has anyone compared the power output of both?

My updated Quad Stealth on level 215 hp netted an improvement of .17 ET and 2 mph in the 1/8 th mile. I still have a slight surge between 35 and 47 + - mph. Its not bad though. I have not run the box on lower settings.Edited by: gmccall
