Here is what I found with the gov mod. the engine will rev a lot more and really puts out a black fog. Yes it has more power and is worth adding the 5 mm nut. It runs as normal untill you hold the pedal to the floor pulls harder in the upper rpms. I have no strange problems with how the engine runs. Here is a pic of the black mark I layed on the road. I now know I have a pos differential two black marks about 12 foot long I shifted into second gear and made one about 4 foot long. I am going to look into a temp gage for the exhaust gas. I don't want to burn up my new engine.
