i think that is even more incredible. I thinkm someone should do more testing of cam gear settings with 272's on the stock turbo. Do you think these numbers in the high 300's cloe to 400 could be achived using the XEDE instead of the AEM setup?

The reason I ask is that AEM says the only time you need to re-sync the timing on the Evo is when you make adjustments to the cam timing with cam gears. Somehow the factory ECU can compansate for shifts in cam timing. I'm not sure why the AEM EMS would need to be re-sync'd unless they're referring to radical timing changes versus the 3-4 degrees being dialed in.

the Cam angle sensor indicates which bank of cylinders are firing, 1,4 or 2,3. The cam angle sensor is significant for injector phasing I believe, but not the ignition timing, at least not with waste-spark and 2 ignition trigger outputs.

Lucky thing is that the aem runs of the crank pickup for timing and uses the Cam as a refrence. So any changes I made in the cam timing didn't change the actual timing to TDC. However if you move the cam timing more than I think 5-8 degrees The Aem will throw a timing sync Erro.
