leaving it at 64.

I am sure there are gains to be had at 70mm, but not worth for us.

Our cams dont make power high enough to need the extra airflow, and you will be restricting the 70mm bigtime as our inlet on IM is only 64mm.

the tsx is a direct bolt on as well, just to let you know.
Thank you, but I understand from another TSX TB thread that there is an "adjustment" to make to the TSX TB itself or the car wont rev correclty in idle. If so, per definition, it's not a true bolt-on. Ufortunaletly, I'm not skilled with mechanic instalations so I dont want to undertake such job. I prefer to buy something that comes ready to use.

The TSX TB's seem to be hit or miss, some work fine, some dont. Any new TB could or could not require adjustment, and ALL TB's will need to be dyno tuned to compensate for the additional air as there are NO aftermarket maps on Hondata or Cobb that account for a new TB.

If you stricktly add a TB and go, you will run lean.

Here is the thread.
