Installed tune on 2012 srt8, car is slower help!!!

This is a very interesting and educational thread -

I'm in the process of tweaking the same settings -

It seems from Mike's response that adding fuel to the max of 10% across the three bands would not be harmful to the engine, correct? If set too high would it just reduce fuel economy and lessen efficiency?

If you add too much you're gonna foul out the plugs. If the electrodes get gas soaked, they won't fire and you'll have misses and generally poor running.

Again, very helpful - thanks -

well...stock calibrations run around 10.5:1 at WOT, you're not going to kill any plugs by adding fuel
