18 psi will be around 100bhp, probably a bit more to be honest, the lda controls on boost fuel, extra fuel that is pumped when u are on full or part boost, where the lda is set determines when the fuel is pumped, the pump quite often needs lots of little adjustments to get the desired power vs smoke, have fun, 130 bhp is quite possible with a standard setup after stage 1 
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
