Hey everyone it's my first time here and I figured I can't really find any answers just googling it so I've came here
This is my first mustang and I've been having fun upgrading it and adding to it. However I have just added the phase 3 roush supercharger to my automatic 2011 mustang gt. I got it dyno tuned just yesterday and the claim on roush was 675 hp at the engine and the dyno at best was only getting 509hp at the wheels. Now the tranny and torque converter and both stock. I understand automatics lose more hp to the tires but I'm losing approximately 25% and wasn't sure if that's normal. If not what can I do to fix this issue? I'd like to get to 550-575 at the wheels. However I am in cali so I do still have cats on for smog purposes. Any help would be appreciated.
