These mods will not increase rwhp to 627 etc.
Further, any shop that uses "standard correction factor" instead of "SAE" is to be scrutinized with a suspicious eye.
A dyno is a tuning tool to simply show the changes in power, torque and air/fuel, etc. before and after mods.

How do the mods actually cause loss of Torque?
