well yesterday went down to dallas to let mark for turbotrix tune my car... for some odd reason on my 2 1/2 hr trip down the car made 20.5 lbs of boost, get it on the dyno... most i can get out was 17.. so we do a pressure test and hear air hissing out the throttle body. mark says its a common proble on 1G DSM's but never seen it on a EVO before. anyone ever see/heard of this problem before?

Yea, appearently it's an o-ring... if it's the same problem. 1g's fix it by rebuilding the throttle body like this;

Maybe these will work, call'em and see;
