try to ask again
has sombody tryed the gm motors 13.5t on the sp speedos with stock software.

or do you now motors that didnt work on stock software.
i dith test the team powers 13.5 and it was not great.
alot of heat in it. had to turn down the setings and it was not fast with the setings down but cooler.
with the same setings as with my 13.5 sp motor it was fast but hot after 2 min.
