Its likely to be a combination of the mapping, turbo and injectors. But it could be one on its own. The engine will most likely be the same.Hi,
Are 3.3 200hp and 254hp engines somehow different? Is it possible to remove limiter by Forscan from 200hp version?
I would imagine, a slightly larger turbo and increased CC injectors, with a remap to suit.
I'd love to see a workshop manual for them both, but guarded secrets at my Mazda dealer!
