Remapped to stage2 but BHP only increased slightly?

<< < (3/3)

Weston:
I'm no expert but I expect the fuel pump will be the issue. My understanding is that upgrading it is recommended for stage 2, although I was told it would definitely need doing.

james:
check ur boost level..  they have prob gone over the map sensor  ... they are nice like that :fighting:
