Roush Supercharger Issue: Please Help

To my Mustang Friends: (RE-POST, ROUSH specific)

Recently purchased over a year the stock 5.0 (420hp) -- 2013 brand new.

Got out of the motorcycle game, and decided to put 20,000 dollars into my mustang.

I did get this done at the performance part a the dealership where I got it from.

List of all mods:
- Stage 3 Roush KIT (should be 650+ HP)-- as advertised
- Hop Kit, with wide tires (for Traction - I can WOT in first gear and not experience too much loss of traction)
- Full Roush Exhaust
- Gauges - shift light, boost, and last gauge can track HP, 0-60 and much more)



FYI - have had the supercharger for about 5 months


Most RECENT concern:
1) Upgrade was done with the best oil and most expensive racing spark plugs (3 weeks back). I do not think this applies to the issue I am will describe. I had tested it after the spark plug change, and it drove with much better throttle response.
Issue: Lately it all of a sudden got very cold in TEXAS ( anyone living north please don't laugh but it has been in 30s 40s.

Given it is my daily driver, there was a week I did not even take the car above 4k rpm. The other day (first time in the cold) where I exceeded 4k rpm in 3rd gear the car RPM was not smooth; WOT at this point. Also tried slower acceleration after 4k rpm. It felt like something was pulling the car down slightly..very hard to explain. 3 words best to describe: slightly jerky, slowed down (pulling down feeling) in rpm gauge (slight skip) throughout slow acceleration or WOT. Seems like the engine was fighting the amount of power to the wheel.

What could this possibly be?
The engine was warm by that point.

Last information which might be helpful: when I accelerated from 1st gear to 4th to redline in this condition, car ran perfect.
However, if from a roll, I have seen these issues as talked about above for WOT over 4k.

PLEASE help me out with suggestions?
Fuel Injection Issue?


Thanks

Rumble defined as car front shakes. After getting it back from the ford I experienced it. Prior to it it was not doing so. A valve line was pinched. Throttle body cleaning and valve flush

Problem solved today. I backtracked and remember a spark plug change along with the oil change

They never took off the "rubber cap" from 1 of the spark plugs on cylinder 3!

So the rubber cap was on the plug, and that cylinder was firing metal to rubber!

All the headache from a simple tech error
