You are actually correct - despite my 10 years of force-induction experience, including swapping/building engines as well components, I am new to the way the e82's get tuned. It appears that there is quite a bit of more technology involved (which as a computer engineer I am happy to see
). Your explanation combined with those of others as to how these piggy backs work make perfect sense. Thanks for sharing the knowledge

Will a tuned 135i with piggyback and full exhaust and IC mods be fast in a straight line? You bet your ass it will...esp. if they both hook up off the line properly...no way a retooled intake, exhaust, flywheel, and LSD beats my car with 60-70 more WHP and 70-80 more lb/ft of torque. |
