Hey guys, I'm a new 2015 FiST owner. Love this thing. It's a power house! Soo much fun to take on\off ramps with. I live in Wisconsin Where the winters are COLD (0-20 degree). So I switched from the stock summer tires, to the Bridgestone Blizzacks ws-80's tire for winter purposes only.

So, ever since I switched tires I have not experienced much power at all. The vehicle feels naturally aspirated at times, and at other times I get that same 'sensation' of speed. I can't figure out what is happeneing. But the vehicle has 4,000 miles on it, and for the first 3,500 miles it was an absolute blast! There is a clear difference between torque (or lack there of).

These are the things I have checked for already:

-intercooler hose clamps. (I tightened all 11 or so clamps so they are tight)
-Tire pressre. (It's all on at tire spec)
-Dealership checked it out. (vehicle did not draw any codes)
-"no"... I'm not getting used to the power this things puts out. (There is a HUGE differernce before and after)
-Traction control. (I've tested on and off. I've also kept a close eye on the TC light and it does not come one. The road conditions have been very dry for the past 3 weeks with absolutely no snow or ice on the ground at all.)

The pulls, and overtakes are not even close to what they used to be, and have not even 50% of the felt power as it used to be. So please guys, I'm dying to find out what the heck is going on with my new car. The dealership employees are morons, they took my car for a day and gave it back stating that everything is fine and the turbo works perfectly fine. But I'm tellin ya..... IT DOES NOT PULL NEARLY WHAT IT USED TO. PLZ HELP ME....

Thanks!

Could be a bad tank of gas. Are you using 93 or 91 octane?

 

[Tyler Schwieso]

All I have available is 91 octane. But I watched Matt Ferrah's video's on the Fiesta. And his is all 91 octane. California octane, which I was told is worse than ours here in wisconsin.

Winter gas.

Sounds like boost hose leaks. Check your clamps! Nothing else would have such a dramatic effect.

I did check the clamps. Is there anything near the rear exhaust I should check?

 

[Tyler Schwieso]

And how come the dealership says that everything is ok and in line? Is that normal?

 

[captainmorbid]

What kind of 91 are you running? Is it alcohol free?

 

[Tyler Schwieso]

I go to BP gas stations and get their 91. couldn't tell you what is in it.

 

[captainmorbid]

Might be worth finding a station that has zero alcohol in their 91, and trying a tank.

Or if BP has none, then you can rule that out.

 

[Tyler Schwieso]

My sound symposer doesn't even have that ripping sound anymore when you really crank on the engine....

 

[Tyler Schwieso]

I did a little research. My gas contains Ethanol. But will that really make that huge of a difference?

Do you have an android device? Phone or tablet, if so for about $30 you can buy Torque Pro, $5 from Google Play store and about $25 for a OBDII bluetooth adapter. https://play.google.com/store/apps/details?id=org.prowl.torque

I bought this one and it works with the FiST, be wary of the $10 ones as they often don't work with Fords.

With this you can monitor your boost and see what the car is doing, low numbers will indicate a boost leak somewhere.

Where in Wi are you ? Gas shouldn't matter that much if you stayed with same gas station. What size winter tires ? Sounds like something is amiss with the boost. Weird no odd noise or sounds .. Mine felt like a NA engine with I popped a boost pipe off but you heard it go and could hear it all the way home at limp mode speed..

 

[Tyler Schwieso]

And that is just it. At times it feels super quick. But at other times, It feels, well.... normal.
Can't really put my finger on it.

 

[Tokendog]

I recommend getting that OBDII adapter and checking your boost PSI. You may be experiencing the times when overboost is not active vs. when it is. Maybe not...but only one way to find out if boost is where it should be.

 

[reddog99]

Could it be just a lack of traction with the winter tires? The tires might be losing just enough traction to take the edge off the acceleration, but not enough to activate the TC. I know my Michilens can spin even in third gear sometimes, on dry roads in So. Cal., and with no squealing, and running regular gas.

 

[Tyler Schwieso]

Reddog.... that might be it! I pulled out of a 2nd gear turn yesterday and went into third. And the car was fast. But it just didn't have that edge to it. When i got out of the car i smelled burnt/ hot rubber. Hhmmmm... any one else have this experience?

I've experienced this rubber burning smell as well but it's actually the chemicals they put on the road for de-icing. I think it is burning up against the hot exhaust.

I found out what is was guys.... sure enough I put my car on a ramp. Crawled under it. and the cold side tube running directly to the intercooler was loose. I retightened it and WAMB!!!!! All my power back! CAn't..... Beleive... that's..... what..... it... was...... LOL
