Have you done any testing using the -4 / -1 cam gear settings that were mentioned by Silversurfer in April? It looks like a couple 1+ users saw some gains. Since I'm currently tuned at -3/-3 with my 264/272 combo, is there any danger from running lean by testing the -4/-1 settings?

 

I think AEM tuners prefer 0/0 - Turbotrix?

Nevertheless - good question(bump).

 

There should be no problem with trying the -4/-1 cam gear setting. We've tested it at the shop but only on a couple of cars so it's hard to come to any definitive conclusions. Give it a shot and let us know what you find.
