um ok there buddy, dont thinkso.things limiting max boost depend on such things as fuel quality, injector sizes, turbo sizes and the general state of engine health.currently im boosting 17psi on high boost with supporting mods, however my fuel maps need major enrichment..........when i get my aquamist in the car i will crank the boost to 20psi and see what kind of power can be made.sarver wrote:12 psi - 14psi
