Mass Air Flow and Manifold Absolute Pressure sensor airflow metering strategies. The US car uses a different one from the World car.

Look in the aftermarket parts thread, there's a list of Europe friendly tuning services (including Mountune, Revo and Bluefin)

So I was finally able to put my car on a dyno this morning. The car with only the MP215 kit put down 188hp/238tq. These are SAE numbers on a DynoJet. I know the numbers are a little lower than what Mountune USA advertises, but the car still pulls strong. The MP215 kit definitely wakes it up. I am happy with it!

Sounds more like WHP to me?

Someone just ran a stock FiST with similar numbers.. Did you run a base line before the MP215? Dynos are pretty much only useful as a delta ie. gains over a baseline. There are too many variable with individual dyno set up and calibrations to compare one dyno to another.

Yeah I'm kicking myself for not getting a baseline. Oh well... I just wanted to get a ballpark idea of what my car makes right now. What my car makes seems pretty high for stock numbers. Cobb's database has several stock cars that put out about 163hp and 204tq IIRC.

Either way, I just wanted to get a dyno pull in b/c I wanted a ballpark idea of what my FiST makes now.

For the record, I want people to know that I love the MP215 kit. It does exactly what it was designed to do, to change the character without sacrificing drivability and your factory warranty. I'm very happy with my decision to go this route.

Quick question for your MP215 owners...

Does anyone have a constantly "dirty" tailpipe now? Seems like my exhaust gets dirtier faster with the MP215 tune...maybe its normal due to the tune being a little on the rich side?

I think the dirty tail pipe issue is more of a problem with Ecoboost engines and more specifically direct injection. There are a couple of videos on Youtube that explain what's been going on with the higher levels of carbon buildup on the valve train of the engine. Ford has in some cases warrantied the whole cylinder head to fix the carbon build-up issue, which is a temporary measure. Hopefully Ford is working in the back ground to find a solution to this issue.

Those numbers sound a bit off to me. Without a stock pull from the same car, there's no way to know how accurate the numbers are, as most people know. The way the car is ran on the dyno can impact it greatly. I've typed up this how-to to help get the most accurate results possible:

Great article on dynos! So what should an MP215 car be putting down to the wheels on your inertia Dynojet given that it's rated at 215 crank HP and unknown torque?

My FIST just arrived yesterday and I am picking up today. I already have the MP 215 kit in my garage waiting to get installed by the dealer. I am actually happy that the torque limiting is still present with the MP 215 as spinning the wheels in the lower gears seems pointless and would affect low speed handling
What did your dealer charge for the install?
