I hear that Volvo merely remapped the HP Turbo computersto get the extra power out of them. If so, does a HP computer plug right in to a normal Turbo car's wiring loom? Any other changes I should be aware of to HP models? The car is nota daily driver, so I can live with buying the best fuel and worse fuel economy.

Im pretty sure theyre two different turbos LPT/HPT.
