When we push the limits we have found that when the boost falls off and does not hold to red line more then about 2 PSI, we have past the efficiency of the set up and it is best to back the boost down to the point where the boost holds within 2 PSI. The dyno does show power levels increase past this point, But at a crazy increased heat levels. Also we have found that going higher then the level where the boost is stable at the track does not offer faster times and in most cases offers actual slower times because of the increased heat. I love the sport 700 turbos and I am amazed at the power they offer at such a low boost level. I look at the fact that they can provide the power they are rated at from such a low boost level as a huge plus.
