Hey guys...the modding fairy has hit me and I have started adding goodies to my JCW HT: AEM Intake, Forge Diverter Valve-Atmospheric, and Forge Intercooler. The thing I'm looking for now is a tune! I can't seem to find one anywhere for the N18 JCW! Do any of y'all know of a company that is reputable and has experience with the N18 JCW? Thanks!

 

Renntech or Precision Auto Werks (PAW). They are basically the same tune since I think Lenny helps both of them out. I have both dyno charts for a GP and they look almost identical. You do have to send them your ECU and its definitely not cheap. That being said, I just ordered a Renntech tune for my GP along with their NGK spark plugs. I also have an amazing Wagner Competition intercooler waiting to be installed as well.

Hey Mike, Can I get additional info as well. Unfortunately, Alta/Cobb isn't compatible for the N18.
