New To Fiesta ST world

[Jack1.1]

Hi,
I am an old guy who just got a Fiesta ST, its a loaded black one. I have a few mustangs and you can find me on the GT500 forum.
My Fiesta has a few bolt ons, just trying to figure out what they are and what they do. I am surprised how light the clutch is and the speed and response on the freeway, it is quite a fun car.
I'm in St Louis Missouri.

Welcome, it really is an incredibly fun car, it punches way above its weight. If you post up some pictures, people on here can probably tell you what your bolt-ons are.
I like your garage art.

Thank you sir, I have a lot going on, I am very active on the GT500 forum as I have a GT500. I have different ideas about the Fiesta ST, first being it has a lot of NVH I suppose that is what it is from looking thru this site, because of the aftermarket RMM. It is an orange/reddish colored piece, I dont know who makes it but is is a larger RMM. The car "lugs" at low speed in 1st and sometimes 2nd gear, then the lugging goes away. I am assuming this is the NVH everyone is talking about. Can't back out of my driveway and take off smooth without the car lugging - best description is its like going 10 mph in 4th gear, the engine lugs. I at first thought I had a broken motor mount until I got on the internet and saw these aftermarket pieces and then looked under the car and there it was so I am guessing I need a softer or a stock RMM.

I don't have anything like that lugging you're describing, that's not normal. My RMM is stock.

yeah homie thats not RMM related. does this new to you partycar have other mods?

It has nothing but a panel filter and an aluminum coolant tank. I checked the spark plugs, they are stock. It has a whoosh upper radiator hose and looks like a cap on a vacuum(?) hose near the radiator that says whoosh, haven't figured out what thats all about. I am new to all this fiesta stuff.
It rocks and the lugging at low speed is worse with the air on, so I rev it and slip the clutch it goes away but does not make for a "normal" driving experience.

What you assume is vacuum cap is probably the symposer delete... You say plugs are stock, how many miles on the odometer? I never had lugging while stock with a RMM, and still don't after a tune and supporting mods🤷🏼‍♂️

My car has 70k miles. I'm new to fiestas, so I have no idea what NVH is "normal", expected, or as a result of RMM.
I do know this, that the car is very smooth once rolling into 2nd - 6th gears, showing strong (relatively) pull at highway speeds.
My car does what I would describe as lugging at low (under 15 mph) in forward 1st gear and reverse, and at a low (under 1500 rpm) maybe this is NVH. It certainly is movement of the engine and is noticeably more intense once you switch on the A/C.
So is the RMM issues NVH apparent at all speeds and all rpm's?
