raise the pressure in automatic transmission lines to increase the speed of shifts
I don't wanna call straight up bullshit on this so I'll just say I am
very skeptical. I'm fairly familiar with my JATCO transmissions. So far,
nobody has been able to crack the Transmission Control Module which is a
separate entity than the ECU. This means that you can't raise the line pressure without directly interfacing with the TCU or manipulate other settings in any other way. The
only way I know so far to increase line pressure is through actual hardware mods done by companies such as IPT (Import Performance Transmissions). These guy have been building and tuning JATCO trannies for a living for a long time. They know the ins and outs. Go to their site. They will tell you the same thing I told you.
So unless Bullydog comes back with a thorough explanation as to
how they manage to manipulate the AT line pressure, I'm going to say it's a false claim and they are banking on the fact that nobody will bother to check if the line pressure has actually changed.
Us Subie guys have been drooling over the possibility of interfacing with the JATCO TCU for as long as I can remember. Don't tell me some off-the wall company managed all of a sudden to do so, when others such as Cobb Tuning or IPT never did.
20hp out of an OTS tune is at the crank and still seems like a high number to me.
