ifyou where going to build your motor then i would say get as much of the chambers TBC coated as poss. these coatings will let you up the det. limits and make the whole engine much more robust, whitsanding lean moents much better than not coated engines.

thanks Chris.
Yep you are exactly right, WORKS, AMS or Buschur might be his answer for this. Each company has their own injection kit but I believe WORKS is the only vendor that takes into account flashing the stock ECU for it with all the saftey measures needed incase of failure. The downfall is that the WORKS kit isn't avalible yet and probably won't be until this summer so it is somthing that you should keep in mind and research.

The other vendors kits have pros and cons between them but none of them are developed to run with a standalone being in control which is why I haven't purchased one. (http://derekdevises.com/) is the only person that I know that makes a kit for a standalone this being the AEM but I am sure this kit could be used on others, it just isn't specific for the EVO it is used in the Supra community.

Hope it helps ya out for some future mods.

After a little more digging it seems and if our WRX & STi friends are also tuning in the mid-10s for good, safe power on pump gas.

Another factor is elevation! I am at ~4000ft where the poor little stock turbo has to spin much faster to produce the same boost as at sea level. This extra turbo speed heats the air more and will make the car more knock prone. Have any of you Colorado owners had to deal with this issue?

A 10.5 a/f on a WRX is pretty safe. I ran 11 on my WRX and ran into knock problems. I have yet to change the fuel mapping on the Evo but I plan on running 10.5 as the highest a/f on 93 octane without water/alchohol injection.
