Going to be changing out the stock throttle body. But I'm unsure of what one to go with. 65mm, 67mm, big oval? Would like to go with the big oval but I've heard of some issues with the tune for it. Any thoughts?

Anyone use a BPS TWIN 73MM T/B??
Ford racing 65mm. People have had surging issues with some of the others mentioned.
+1. This is what I remember reading about most (all?) reports of surging, which seem more tune-related than hardware-related. Choose your tune carefully......As mentioned here in post # 10, and in other threads.....issues with the mono-blade turn out to be " tune " related.
Thanks for posting results John.Just tonight I just installed the frpp res delete. Airaid filter and ford 65mm throttle body. No tuner.
I dynod this on my dynojet Dyno
Stock was 579
Frpp and afraid filter was 604
Frpp, airaid, ford 65mm was 633.
Now adding a proper tune would net quite a bit more I'm sure. I just wanted to see how it would perform with simply bolting on the parts.
Only issue is Its a 2013 gt500 convertible and Dyno run in 4 gear will shut me down at 6300 rpm at 155 mph So there may be a few more hiding once the tuner goes on and I can pull to 7000 in 4 gear.
It runs perfect. No issues at all. Air fuel is too rich at 10.5-10.8 with the stock tune. I can tell the torque picked up from 2000-4000 range.
I have a sct x4 tuner and this coming week will be installing
