    Correction factor. A dynojet is the only dyno out of all the brands where there is no way to add in a user defined correction, in addition to standardizing factors such as SAE, DIN, etc...

    A SAE corrected mustang dyno generally reads 10-15% less than a dynojet, making your numbers even more awesome. Your car must be a hoot!

    I know that dyno's don't really mean anything unless you're using it at the same time to compare modifications. That's when you can truly see the differences with the same conditions. Other than that I guess the only similar way to compare car to car across state is just doing a quarter mile even though elevation and weather could play a slight role in the final outcome.

    So I got my car dyno'd at Mid Ohio a couple of weeks ago. 2 pulls for $20 for charity.
    The weather conditions were almost perfect: low 70s low humidity... So I'm wondering why my car only pulled 193 HP..... Especially since I have Dinan CAI, throttle body and stage 3 software.
    I was hoping to at least see it over 200 hp... Also I was surprised to see maximum torque so high I thought max was at around 3500 RPM.
    Also there is a strange dip at 4k... I think that's the disa transition... i already had the DME done for that.

    Wow...that dip issss strange at 4k. What could it be?

    Looks like you have >15% power train loss. Dyno accuracy may be playing a role as well.

    I'm thinking of going back to the place that installed the Dinan stuff and saying WTF?

    You know, I can feel that dip at 4K too... almost like a fluttering, that's why I'm thinking DISA. I had it out twice and it looked ok though...

    Have you replaced your vanos seals? That could be causing your dip and any loss of power at 4k rpms.




    EDIT* Yeah, I forgot it usually causes a power loss around 3k rpms not 4k.

    Bad Vanos seals shouldn't cause power loss or dip at 4k.

    Vanos is typically loss of torque/power down low followed by surging at 3k, iirc.

    I replaced the VANOS last spring. I haven't had the time to talk to the Dinan guys yet. Been swamped at work...
