More questions on Turbo kits

easy to step up the boost, add a boost controller or a regulator and you can turn it up as high as you have the motor built to take,
what you can't do is make less boost than the wastegate is set for, usually best to keep the boost level low and step it up gear based ,
once you turbo its no longer how to get more power,more how best to use what you have.
