Its right in the tephra v7 thread thought you looked through that since your mentioned the v7 tephra patch.

The car seems to stall coming off of the gas.
Fuel consumption is bad (as compared to the v5.10).
Cold starts have the idle all the way up to 2100 rpm.
The idle is ruff.
I believe this might have to do with the wacky LTFTs.

Just out of curiosity does the evo 7 have an EGR?

Most of these at least in the 8's were issues when the EGR bits got turned off like they i believe are in that version.

I know there was a big thread on poor cold idle from no EGR.

I think you had to mess with the cold ignition trim table and some various other tweaks to make it right.
