Hey Guys,
i just brought a r33 gtst with rb3025 in it, motor has been rebuilt around 20K ago with fCP pistons, spool rods, nitto pump etc.
turbo set up is a garrett GT35R T3 0.82 external gate. running ebay exhaust manifold & wastegate & 3 inch exhaust system.
here is a dyno graph i got when i brought the car looks to have a slight boost drop, and very wavey boost line is this normal?
or could that be casued by the shit manifold & wastgate? or the 3ich exhaust system?
