i installed an anderson boost pipe on my stang and now its running pig rich , it used to run at 11.7-9 by 6k rpm but now its running low 10 with slight pinging , boost seem fine , i gained 2 psi and the boost is coming up harder than usual , why should it run this rich if i am cramming more air into it? is it losing metered air somewhere?

You're running 10:1 AFR and pinging now?

If you go back to the original setup do the symptoms disappear?

why the hell are you running it while it's pinging?

There is something wrong here....what is the timing? what octane fuel?

its only pinging at wot and i ran it at wot once since i posted and talked to my tuner , it seems like i had a leak and car was drawing un-metered air that was caused to run fine before because it leaned out the mixture but now with the leak gone its pig rich , will do a re tune and see what happens.
