Hi people,
I recently purchased a p38 2.5 diesel and so far its been great! Touch wood!
Anyway in my quest for a few extra horses and torques i popped the bonnet to check the air filter wasnt blocked. I discovered a k&n panel filter that was fairly clean. I also noticed a shiny blue box sat in the top right hand corner of the engine bay. On closer inspection it is a psi motorsport box a vp power one. The thing is ive researched these everywhere and cant get a definitive answer as to how, specifically, the vp power box works. Anyone who has one please enlighten me as my power delivery is a bit all over the place. Ive read that some are adjustable by a screw some by an elaborate pin system i cant understand!
Please help
