2021 Explorer ST

I bought a 21 ST fully loaded at 15k miles in April. Its been great so far but I've been thinking about modding it. I found a shop not far from me which does upgrades specifically on Ford vehicles and I'm considering getting myself one of the mod packages. These are the two I'm thinking about,

https://www.teamjdm.com/explorer-st-stage-4-performance-package/
https://www.teamjdm.com/explorer-st-stage-5-performance-package/

Its supposed to give me 120-130+ HP and 150+ TQ on 93 Octane.

What I'm most worried about is whether this is gonna bring down the reliability of my vehicle. I use this car for my daily 40 mile commute and its my daily driver. Its mostly driven on the highway. I know doing these mods will void my warranty so how worried should I be about reliability in general considering that Ill be doing all the required maintenance or whatever is gonna be needed, perhaps more frequent oil changes and such. Thanks!

Reliability will be perfectly fine. JDM is not the best tune, ZFG Custom Tune is best. ZFG sells a Stage 1 pack that is the best starter package. Here is a modding guide that should help you out with modding these cars:

I spoke to them today, they seem pretty knowledgeable especially when it comes to the explorer st. They said reliability shouldn't be an issue. As for the tune I've seen good reviews from them, also I don't really do any extreme racing anyways so I don't need something super competitive.

Yes Adam at ZFG holds all the records for the fastest STs so he definitely knows what he’s doing. Reliability will be perfectly fine.
