Quicker Spool
Reduces turbo lag for sharper throttle response and harder acceleration throughout the rev range.
OEM-Fit Details
Correct O₂ bung locations, CNC stainless flanges, and TIG welds for a true bolt-on install—no mods required.
M274 ECU Tuning: Eliminate CEL, unleash full boost, and add serious horsepower with razor-sharp throttle response. See Tuning →
