Tow shift points to install on 87 performance

[Cthecountry]

I would like to know what the tow shift point settings are so I can install them to the 87 performance ?
Reason is for my 2003 Gmc 1500 with 5.3 the tow settings on Diablosport Predator 2 cancels out my trucks
Engine Braking.
I need engine braking towing mt 6k trailer to help preventing brake overheating and engine braking
(engine Compression braking) helps to slow down Descending from a hill.
The 87 performance keeps the engine braking but does not have the towing shift points.
Thank you Paul

its tricky....and not that simple.

but....there should be a param called tp rel vs upshift or something along those lines?

adjusting that will change how long it holds each gear at part throttle, which is what you are after. Try making changes there to get it to behave how you want.


Thanks

Thanks , I like the tow setting But to remove engine braking ( engine compression braking)
Is crazy for towing.
I'm used to using Jake brakes on a semi.
It really helps slowing down while towing 6k trailer without using brakes and overheating the brakes.
Guess I'll just have to play with shift points on 87 performance ag least the engine compression brakes will work.
