Will there be a large loss of boost after replacing with the ATI Super (supercharger)

Hello! The current setting is A2a sc/9lb pulley/turbo guard and boost is 12.5 psi. At 91 octane , 530whp. I also purchased ATI Super Damper(#ATI918584) when I rebuilt the motor.

Default Will there be a large loss of boost after replacing with the ATI damper

Hello! The current setting is A2a sc/9lb pulley/turbo guard and boost is 12.5 psi. At 91 octane , 530whp.

I also purchased ATI Super Damper(#ATI918584) when I rebuilt the motor.

How much power will I lose if I install the atidamper?

I want to know how to compensate for the falling boost. Do I have to retune my ecu? Or should the hardware be changed?

None, same size as the stock damper if you bought the right one.

I guess I would question the desire to put one on...? To gain power? You would lose power.

Yes, I gave up upgrading the damper after consulting with the mechanic. I decided to go when I switch to Turbo in the next time
