That makes me feel good that you guys are getting the same power for the seperate throttle body and plenum then the 78mm throttle body plenum as thats what I have. I never had any issue with too tight of screws or stripping anything luckily!

If you have a 18V or better screwdriver/drill with a torque clutch you can often use it as a sort of low torque impact wrench--just set the driver's torque to a high setting and let it bang away on the screw. I have found this works great on things like the TPS screws on our cars, and other absurdly tight Phillips and socket head machine screws.

The only thing air related that will ever increase power is the weakest link in air flow. That's a fact. Kenne Bell doesn't even bother selling a TB or upper intake higher than 75MM even for a kit at 14 PSI for the 2V 4.6L New Edge. Something about the fact that a 75MM TB @ 14 PSI on a twin-screw supercharger will flow everything the engine can ask for tells me a 78MM is worthless both FI and N/A. But i'm crazy like that.
