The tune would be about the same with or with out a valve body , I would need your ECU code but the valve body helps more with the ECU codes that we dont have full ATX access to all things through the tune , there is only a few ECU codes this happens with and I wouldnt think your year Focus would be one of them
I would start with a tune as your going to need it for the engine anyway then add the valve body if needed

Lentech can do a manual valve body with a trans brake as well , I had this combo on my 700+ HP ATX Focus

harrison.mike.j Well I asked the question to Chris at Lentech and he responded:

"The tuning does a good job of firming shifts and setting shift points. The valvebody helps with holding pressures that some tune files do not address and helps longevity."

If you need more I would look into Lentech Automatics then did the ATX in my car that held 723HP and ran a best of 10.95 @ 137 in the 1/4

emsvitil e probably means

electronically controlled

01svt_sedan The code of the transmission provides info on what type and how much the transmission is rated for. I read this a while ago so correct me if im wrong. 4f27e. 4-speed, FWD, 270 divided by 2 gives you max torque. Dont remember what the E stands for.

Tom can set you with a tune and synthetic ( Mobil 1) ATF fluid helps as well.
I've recently decided to go mild NA rather than mild turbo build (my main concern about the turbo build would be running higher octane fuel$$) so it's reassuring to hear that you can get some good low end out of it. Your list of mods sounds similar to what I'm picturing but with some stage 1 cams. What kind of mileage do you get? Thanks for the advice guys!

EDIT: After reading around it looks like I'm going to end up running higher octane fuel anyways. Looks like any mild build with a tune will require higher octane. I read there's an 87 octane tune available but I have a feeling I won't be satisfied with it.
