They're running 20-21psi peak boost, tapering a couple psi towards redline. As for mods, the 300-310whp cars are running our full exhaust, camgears and XEDE engine computer. The 270-274 whp car is basically stock with an XEDE. The 280ish rwhp car is running a 2.5" cat-back with test-pipe. The a/f ratios are purposely conservative since they are expected to put up with hard driving, not just 1/4 mile sprints. Plus, with ignition control, we don't have to lean the heck out of the fuel curve to make power. Plus, ignition control allows me to message the underlying spark advance curves in order to maintain a stable safety margin against. This is reason for the good run-to-run consistency very good despite a reasonably short 30 second cool down period between runs.

Shiv,

Is there an XEDE map available for stock EVO8 with
just K&N or other aftermarket filter?

Thanks
