I am looking for low 500s whp and mid to upper 400s wtq. I believe in very spirited driving, but the car will not be tracked. If the current wastegate settings show promise, I might be good with the 8.7 psi that the test car is currently running. I think that emissions will be the deciding factor, as I have to do OBD II testing (but no visual or sniffer) every two years starting this summer. The dual 100 mil spec cats that Sasha designed will help. I currently have Fast Intentions HFCs and Fast Intentions Cat Back Exhaust, but I would likely sell that exhaust, as the HFCs would not be of any use. That's why I also inquired about the full exhaust pricing. Do you believe that a defouler connected to the o2 sensor would allow me to show all sensors active and supported?
