No Power!!??

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....

Holy crap! I don't know if I'd go back to that dealer service dept! Glad it's sorted.
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
I think I might be experiencing this. Could you post a pic of the "cold side tube"? Thanks!
Tyler Schwieso...You are a savior among men. This is the cold side directly off the intercooler. As you can see in the photos, the threading is exposed showing the hose sliding off. I'm glad this didn't pop off with my wife driving or something. Btw...this thing is an absolute pain in the @$$ to get to and tighten. However, once I placed it back over the threading and tightened it down, took her out for a drive, and WAMB is right. It is worth noting though that it took a few minutes of driving before I noticed that things were normal again. So, be sure to drive it for a bit before jumping to conclusions.
