B&M shift improver?
anyone use a B&M shift improver? does it help the tranny shift better...cuz mine shifts like **** and at bad times and for 30 bucks i figure this might help out...any advice?
authority to do is increase the part-throttle
line pressure out of the PWM valve. WOT,
it should already be 100%, no gain. Shift
point, the PCM determines, the plug-in has
no clue until the command comes.
All of this is better off being programmed at
the source.
