the ratio depends on how much boost you want to run and what your base boost is(wastegate setting)...

gain i have at 100percent and some other have mentioned it too..

What wastegate and base spring do you have? That will determine what percent you need to achieve 18psi. The gain is how hard the boost comes on or how fast it reaches your entered percent. Personally, I like it close to 100% and haven't had it overshoot or boost spike.
