Heard today that BPC tried a set of 'Stage 1' Supports and found +5hp across the board.
IDK if that was with stock tuning or with added tuning.
Dyno graphs to follow.
I sent them a set of 'Stage 2' with an additional 0.4-0.5mm lift to try.
Not too bad as +5HP in these engines is hard to come by.
Would like to see these on a N55 engine too.
