Thanks,

25psi with what turbo ?

25psi with a std T3, is not going to be the same as 25psi with say a GT30.

Extreme example I know, but Woodford say that that chip is fine for a std T3, and a T34.

The guy who owns it also phoned PJ, and they pretty much said the same.

How can that be possible ? It makes no sense.

The 2 turbos will fow different amounts of air, even at the same boost pressure, so one chip cannot do both, as MAP is the main load reference.
