Assist Hks

is hks ssqv bov bad for 1.8t?

I know i’m supposed to get the forge DV/BOV…this assist stock. The HKS SSQV gives me a chubby! I hear this is bad…messes up comp, turbo lag, and turbo stress, not to mention loss of power. Is there a way to remap the stock ECU to put out more boost to supply aptmospherical blow off. I have 01 jetta 1.8t stock w/ short ram intake. ?? How bad would this move b????

DONT GET ONE! It’s not the right thing for your engine.
How can you possibly consider doing it if you know it messes up those things?
It actually does do that so what you hear is right btw.

Since you have the same engine as the audi 1.8t read the following:

The Audi turbo system is a closed loop system by which all unused boost that is spooled during off throttle and gear shifts must be re-routed within the system; it cannot be vented to the atmosphere due to the dependence on the MAF and ECU to properly read and interpret air flow dynamics within the intake tract. Therefore BOV’s (Blow-Off Valves) are not used because they create a rich air/fuel condition (i.e. less air to fuel ratio) which will damage the catalytic converter, create soot on the exhaust pipes, and cause occasional misfiring (due to the purged air) which will result in ECU miscalculated timing adjustments and other errors.

For Audi closed loop turbo systems, a BPV (By-Pass Valve) or DV (Diverter Valve) is needed to recirculate the purged air and keep it within the intake tract.
