Towing a 5000lb trailer @ 60mph with a ambient temp of 70deg I was seeing 199deg trans temp. It was barely working, level ground and was quite surprised to see that temp. What is everyone else seeing for trans temps while towing, especially if heavier loaded.
Also what is the Boost in lbs the EB makes? I do not see it in any literature or elsewhere online.
What is best tuner to buy for the ecoboost? I see a few with SCT.
How about actual horsepower gains with tuner, exhaust and air improvements?

Pulling our camper(7500lbs) depending on how big the hills are the temp runs between 190-200. I think the boost level is around 13-14lbs. I wouldn't chance putting a tuner on it until the warranty is done. Ford wont show you the time of day if they knew you had a tuner on it.
Those trans temps don't look out of line. Mine reads 190 just cruising down the highway unloaded.
I read somewhere that max boost was in the 14lb range.
The EB is already engineered to squeeze a lot of power out of a small engine. One is taking a serious gamble by messing with it and there isn't much to be gained.
As has been said, tuner will void the warrenty if you have an engine failure. Acording to my service manager, the first thing they do on a blown engine is send the computer to Ford. Ford checks and can see if it has ever been tuned (even w/ a handheld unit). If it has, no warrenty. Of course this would only apply on an actual blown engine or turbo. Anything else external and they would probably never know.
