hi all! it's my first post here!

i have build a tune with exhaust brake and it's working fine but i have to downshift in manual mode! so i headed to my tcm and i put more aggressive number at downshift at 0%tps but it's almost doing nothing! i have read that we do not actually have access to full downshift table that why my downshift are slow! anyone know a way to have more aggressive down shift? or when are we gonna have access to those timing table?

thank you!
