    So, went to the dyno the other day, to see what i'm getting. Unfortunately i never got a baseline when the car was stock so hard to tell the gains. Car is a 2017 GT Manual, with FRPP Touring catback, and Ford Power Pack 2

    I went in with the intention of getting the most realistic real world scenario number i could. So the car was heat soaked, had the A/C on full, stereo and lights on (maybe a tiny bit of alternator load ???), hood shut. The red pull was in 5th, the other two in 4th, as we hit the speed limiter. Not sure why the 4th pulls are cutting at 7000 though as in theory the rev limiter should be 7300 with the PP2 tune. Anyway even though the 5th cut, it looks like it was peaking anyway so wouldn't have seen much more than that i think.

    Also, according to the AFR gauge on the car, its running really rich. Starts at around 12.5 in the lower revs, but by the time i'm at 6000 its reading 10.5 which in my eyes is way too rich. Is that normal for the Ford PP2? I've heard Ford Performance run the tune with quite aggressive timing, but do they try to make it safer by running really rich? I can only assume the AFR gauge is correct because whilst cruising it reads around 13.6-14.1 which is about right. Need to datalog to have get a better view on what's going on.

    The owner also said his dyno forgives nothing, meaning its a heart breaker. He says a few bone stock M3's and Audi S4/S5's (which are his main business) all read around 20-30 hp less than the claimed factory output. I don't know if he was just saying that to make me feel better.

    375PS at the wheels, which is about 370hp at 32oC, which is 90oF.
    Calculated 423PS at the crank which is about 417 hp.
    Dyno is calculating a 12% drivetrain loss which seems to be about right.

    The PP2 tune commands mid to high 11s (same as stock) so yes it's very rich and very safe. Although it shouldn't be in the 10s, that seems a bit extreme. What did the in car readout say?

    The in car readout was what i'm referring to. Haven't had a chance to datalog yet.
    So yeah, starting at 12.5 and ending around 10.5 by 6000 rpm according to in car readout.

    Looks like the cat over temp protection kicking in just as its programmed. I'll dble check those tunes but iirc cat overtemp comes in at 4th gear above 6k. Plus certain temps
