I agree Darren, my old Sigma went well though, the day it got dynoed, Sam Barker was following me in a HDi that was supposedly 130bhp and it left that, I personally think about 140 is about the limit on a stockish setup
Phase 1 D-Turdo, K14@24 psi, De-cat, meaty backbox, Bosch pump, grinded LDA pin, duel air fed K&N =133.7bhp & 188ft/lbs
