That's good to know. I don't know why it held better boost then. I'm just going to eliminate the turbo as a possible cause by throwing on some 15g's. I'm going to send these 13g's out too to get them checked. I originally bought them from Carl McEwen back in 2004.Stock catback is only a 15 hp restriction at 600hp, probably not it.
Also you should be able to hit full boost in 2nd gear easy. I hit 95% of my setpoint in 1st, 3rd is absurd to be checking on the street.
