Trans hunting for gear.
 

Trans cant seem to figure out which gear it wants while accelerating onto the highway at say 3/4 throttle. It upshifts to 3rd and downshifts to second several times until I back the throttle to 1/2 or less, then it shifts like normal all is well.
Seems like the upshift and downshift point might be crossing over... but IDK
Currently running the 100HP tune from PHP. Everything else is great.
Any advice is greatly welcomed.
