NorCal to MO and back 4446.1 miles avg. 15.77mpg.

Prior to trip ran just under 13mpg.

Three tanks of gas since trip avg. 14mpg.

This week or next will install Tornado using 14mpg as my base number I'll run four tanks of gas and post the results here.

Instructions for Tornado say it must be installed prior to the MAF at either end of hose. Seems to me best result would be if you mounted it at the MAF end of the hose. So to answer your question, Piper, it would go before the IAC valve or motor.
