Ive got a forged actuator . And its worth me getting it mapped then . As the ppp map the gb270 s come with its pants me thinks . Its hitting 1 bar 14.4 .psi . ish and then tails off to 12 psi .
Im trying to keep the car original Ish lol but want it to drive a little better
It won't drive better with more boost on that tiny little turbo.
Leave it alone and enjoy it for what it is.
That turbo is better suited to a 1.6 than a 2.0, let alone a 2.5!
