    So the dyno operator took the car to redline both times.

    Redline is 5522rpm
    3.73 gears
    27.18 diameter tires (235/55r17)
    3rd gear pull in D3 setting (1:1 for 4l60e)
    Peak power was at 97mph on the dyno printout and redline was 112mph

    I calculated redline to actually be at about 120mph. The whole power curve looks normal but maybe a little too broad and shifted 8mph to the left. Could the trans be slipping? I know the 3-4 clutch is what goes earliest on these things (it's what went in Gma's 4l60e) so I wouldn't be surprised. I think he's set on the T56 now lol.

    Also, we took the car out last night on some back roads and I can now say HOLY SHIT I didn't think a boat could handle like that. He needs a rear sway bar still and something thicker up front, but it handles very nicely.

    Converter wasnt loaded probably. Happend to me at dyno day. Thats why i usually do what ray at dyno day says and run it 2nd thru 3rd, so 3rd is loaded correctly

    Stock converter? That is good to know. We were gonna take it out on a datalog run to rule out any slip.

    @SSlowBoat

    This car was a 96 but was converted to OBDI, tune is based on Grandma's stock tune (95 Roadie). I didn't think about this until now, but is there a chance that the PWM lockup nonsense is screwing with the trans and causing slip?

    I have been looking at datalogs and was using the engine RPM and trans gear to calculate an expected MPH the car should be at past the 1400rpm stall speed at any given time. What I'm getting is really strange though because the actual MPH doesn't correspond to the calculated MPH a lot of the time. Either really bad trans slip or the converter isn't locking up as it should.

    Forgive me if this all sounds really stupid, I am illiterate when it comes to autos.

    edit: I did a bunch of reading and I think I misunderstood how the converter works. So 1400rpm would only be the maximum allowed rpm difference between the engine and trans input. Going to make a plot of % converter slip and compare it in each gear. Could be that the trans is good, motor might be having problems. Doesn't really matter though, the cam is going into the old TA shortblock and getting dropped in eventually. He is also eyeing up a junker Formy with a T56 to part out so the swap would be pretty cheap.
