Abuse mod ?
Is it safe to modify the settings in this window?
This is on a 2000 Super chicken by the way. It turns 13.3 but we know it can do better with a bit of tinkering.
Thanks for the replies.
I made the suggested changes in the engine calibrations but for some reason it is not shifting as high as it used to and that window when you first open the transmission section has me thinking.
I will ignore it for now and try raising the MPH a couple of mph and see what that does.
Thanks again,
Neil
