The 991 needs 4 wheel dyno or it enters limp mode. At least what I read.

I had an E39 M5 years back and to defeat limp mode on the dyno, you could pull a certain fuse. Don't know if that is applicable to the 991.

Update: you need either an Autel or a PIWIZ scanner to put the car in rolling mode. Otherwise the computer kicks in and the PSM tries to stabilize things with the rear brakes. This is true even on an AWD DYNO. We ended up across town on a Mustang AWD dyno but if we knew to put the car in Dyno mode then the 2wd dynometer would have been fine... lesson learned. 20-25% loss to the wheels on 3 runs. Not bad.

S. No mods. Yet. Well, that’s a lie. It has clear LED side markers and a sticker.

Admit it ! This is a cunning attempt to lure Sticky/Fancy out of his lair under a drag strip.
