Has anyone changed out there plugs after installing a Dinan or NM tune moduel? Does going with a colder plug help?

 

I was wondering the same thing. I am installing my Dinan Elite this weekend.

 

Did you get it installed and what do you think about it?

 

I did get it installed along with a NM cat-less exhaust, and a Forge FMIIC along with new engine mount and chassis braces, and an AWE carbon intake, and NM short shifter. I would say the jury is still out. I don't notice much if any power gain in the lower RPM but between 2700 and 4500 it seems to generate decent power. I am going to be updating the suspension with coil overs in a couple week and new NM anti sway bar so I am hoping this makes a difference. I am also going to fill up with 100 octane today and if that helps. Hopefully there is juts a short learning period and it will continue to build power.
