  1. I think that words used in video needed to have more careful consideration:
    1) there are no bigger MAFs, just bigger MAF HOUSINGS.

    2) when you talk about _moving_ temperature sensor – I might be wrong, but those MAFs seem to have internal temperature sensor – so it is not really about moving, per se, but installing additional air temp sensor?
    3) when you say that you are installing air temperature sensor where air is colder… I am not sure I follow logic – because why skew temperature readings in other direction(as opposed to heatsoeked current sensor)?
    4) dyno printouts. could you calculate areas under torque graph(sorry – my English is bad and I don’t know the correct term)? that would show gains (if there are any) for torque. otherwise max torque hasn’t changed and those 5hp on 360 (~1.38%) might be just measuring error on dyno.
