    Finally found another company offering an ECU reflash. I am curious how this compares to the DynoTronics Reflash (Which I would never do, considering the past complaints)

    I wouldn't jump to such strong conclusions with the information available. There are too many variables to compare dynos from different sources. For the best results, the two models would need to be tested in the same conditions with one test after the other.

    You also mention the model you are comparing has a CVT. Dynos for vehicles equipped with CVT transmissions are inconsistent due to the dynamic gear ratio.

    Regardless of comparisons... barely breaking 100whp with I/h/e/p/tune is depressing.


    This is the j20b dyno I spoke of... which notably seems rather high. Never even occurred to me till you mentioned that the cvt's can be inconsistent on the dyno.

    Agreed. The testing done in that thread can be helpful in comparing modifications providing similar conditions were replicated.
