I have an 03 Tdi Jetta with 70k miles on it. i have the kermatdi powerplus 520 nozzles in it. i just ordered their q-loader chip, their "the hammer" turbo and a vr6 clutch kit. I know the turbo can handle 25+ pounds of sustained boost. but i was wondering how much the stock motor can handle without having to worry about blowing anything up. it is my daily driver . i told them to send me a tune that limited the boost to 20 psi. i plan on owning this car for a very long time and want the motor to last. is 20 pounds too much or will i be ok?
