So thats 3 engines now, 1 with definitely SOTP change, 1 with maybe a slight change and 1 with no SOTP change detected...

What did the civic end up doing for mpg's?

Yesterday I tweeked my tube setup, went back to the 9" piece connected straight to the manifold. Looking to get power up the rpms a bit. I am finding though that with higher rpms, mpg's seem to be better than lower. That is a head scratcher for me. With the current setup, trans still wants to upshift and cruise at 1400~1500 rpms at times which tells me there is still a good bit of bottom end boost, even with the attempt to shift the power up the rpms.

On the jeep, its update is delayed...had issues over the weekend and a 180* stat went in during an engine flush. Going to wait until I hear back on mpg's with the new setup. I expect it should still be in the 14-14.5 range.
