people here are confusing everything. I'm not boosting 27 psi all the time, just for a few seconds as a spike that problably last 5-8 seconds probably less, after that the psi goes back to 18, 16, 15, 14 what ever boost level i programmed the Electronic boost controller.. lots of people says that this turbo its not capable to boost so much, problably not for long or to hold, but any turbo if you disconect the hose from the wastegate it's capable to boost as much as the turbo can blow. in these case 27 psi.boosting so much doesn't mean it can hold it, don't get me wrong. i can't hold that amount all the time, but having this setup to spike 27 psi for a few seconds is like if you have a NOS kit that you juice it a little of it for a little of it of time. I've try all of the setup posible, By just Boosting 16 PSI all the time, no spikes or nothing. and let me tell you buddie it's not the same thing to step on the gas pedal in 3rd gear and just boost 16 all the way, than steping on the gas and boosting progressively 27 psi, then go back to 16, 17 , or 18 which ever you like the most you get a massive agressive power and torque at mid-high rpms
