I think about establishing a 'baseline' for my 991S before I do any kind of modification on it. I have very limited trust in dyno's, except to a certain extent for comparisons when the measurements are repeated in very similar conditions on the same dyno.

Anyway, I have been recently told that, because of the latest PSM, the car would limit the power if it senses that there is too much discrepancy between the front and rear wheels (this would certainly be the case for the Dynojet I have used for other cars).

I am not sure this is correct and would like to now if other forum members have already successfully dyno'd their 991's?

Thanks!

 

It is absolutely correct. I tried to dyno my car yesterday on a dynojet and the car would not give full power and would not let me activate sport or sport+ modes. Not sure how to get around it. Hopefully someone will chime in with a fix.
