this DIY is a very involved DIY and it is dangerous. Too much pressure can kill ageing seals.

The fuel saving I got wasn't much but the firmer feel of the box was a nice upgrade for me.

Do at your own risk.

Thanks, I will put this project on the back burner for now. I am leaning towards the intercooler and chip upgrade for now. I will consider the A/T pressure change when I service the gearbox again, I recently replaced the A/T fluid and diff oils.
