Exactly what performance gain do you expect to see with the spun aluminum CIS version of the Tornado? I'd be glad to dyno one for you but I'm not sure what significant benefit this is for a sub-350whp 930. You would need to tell me exactly what parameters to measure. I assume AFR, HP and torque throughout the operating range.
Also, does installing this device on the metering plate require a re-calibration of the plate?
The performance gains are more for engines with upgrades as opposed to stock motors. The whole idea is to get full travel of the MP arm which allows more fuel into the engine during higher boost levels. I think someone here who dyno'ed an engine said that at full boost they were able to flood the motor just by pushing down on the stock MP with a screw driver. So there is much more full to be had and this spun aluminum version allegedly allows it. The beauty of this thing would be in maintaining the CIS without all the craziness of EFI. Blame it on the economy. LoL
