Here is my quick review of both throttle bodies. 2016 Z06 M7 BMS filter
Both are a improvement over stock, however Tony's TB IMO is just better at slight throttle openings and especially first gear engagement from a stop. With the Katech and stock I had to keep the exhaust in sport mode so I could hear it and not stall the car which I did once or twice (embarrassing). In heavy throttle use and higher RPMS they seem pretty close.
Its not a huge difference I would say its about 10-15% better. With the drivability being my main goal.
If you look at the pics below the Katech has a little edge on the lower side (right of center) where the Mamo is smooth all over. The Katech does have the bracket on the flap machined down which is a nice touch.
I've had my Katech on now for several months. Drives perfect with no part throttle hesitation. And with the shaft milled down must have an increased effective flow area.

I have been driving on the Katech with my M7 Z06 for about 10 months now. The car's drivability is much better and any lag or hesitation at takeoff was eliminated with the mod. May be the best mod to date for me.
just asking... whats the difference in driving oem/aftermarket?
i don't have any problem with the oem throttle, if it's better, can you explain why? i might get one need more info's
You driving an A8 or an M7?
On an M7 the off idle hesitation (flat spot) is very apparent and these porting jobs correct that issue. I can't comment on the impact on an A8 because I've never driven one.
