There is something wrong with the rpm reading on this chart, peak torque, peak power and the rev limit are all occuring about 500 rpm early. Rev limit should be 6750 not 6200. This will certainly effect the readings.

Open the lid, if you have a large radiator like thing with INTERCOOLER written on it I may know what's going on.

Here’s a dyno from a well maintained pretty much stock 964 (exhaust only) this is a very reliable number from a shop that does a ton of certification dynos for race cars that are consistently verified with othe dynos during events, ie conservative, no BS dyno. At the wheels, this one has no smoothing so it looks ragged but the numbers are the same regardless of the chart graphic. Three pulls. The highest 254hp/223fp, this is about what I’ve seen on all my 3.6 in stockish tune. A chip on this car will be in the 260+Hp and +a few points on the torque.
The surprising number on your car is the torque, as someone mentioned above it’s pretty obvious you have cams and most likely chipped as well. I would look under the seat for a sticker on the ECU, and/or is there a warning label for minimum octane under the fuel door? That work could easily be done for $10k in the day. Not unusual to change the rev limit, and it’s a torquer can grind. So enjoy! Should be a fun car to drive!

^^^ on a dynojet my car shows 241rwhp on a mustang 209rwhp. the curves are nearly identical just different numbers based on how the unit perceives it. tested a fresh 993Vram same day and numbers were on par with what I would expect from the mustang and a 993 Vram. Peaked where the v-ram came on and power was consistent with factory numbers. Although we use an 18% loss with the mustang and 15% with the dynojet. I have seen many stock cars on the mustang and they all fall within 10% of the factory numbers. The mustang usually leaves most a bit disappointed.
