#9008, "RE: Greddy Type-S Settings" In response to In response to 3
From RRE's experience, the factory setting (from Greddy) is wheer you leave it at. Unless you bought it used.
Like other's said, be careful of the thread. Easily stripped. And becareful when closing the hood. make sure the adjustment screw doesn't come in contact with the hood.
Tune to where the valve opens completely, and no compressor surge between gear changes, and sudden throttle lift off. It is normal to get SLIGHT (and I emphasize slight) surge here and there.
