So I just picked up a 2022 st and I want to make a some good performance upgrades. Anyone have any suggestions for me. Im looking for more high end quality parts. I don’t want to go cheap on my baby
Your very best "bang for the buck" is a tune. Most would recommend ZFG (zfgracing.com). There are numerous dyno results on this forum where he has achieved approx 100 HP over stock with a custom 93 octane tune. For about $1k, there is nothing else that compares to dollar/HP ($10/HP)
If you don't have the four bolt rear end (later '21 on), a rear diff brace is good insurance. The ID Speed or AWR part are the best out there currently. Although it won't actually add HP per se, an upgraded intercooler is also highly recommended for both consistent performance and longevity. There are now three- Whipple, CV Fab, and Mishimoto. The Whipple is proven in tons of installations, but is expensive. CV Fab is the new guy on the block and is cheaper. Since you seem to be less concerned with a budget, I'd recommend the Whipple.
At this point, you're driving an ST with approx 425-440 wheel HP. And if you elect to go with ethanol, an E50 tune will net you 475-500 wheel HP.
After that, the dollar/HP factor will go up dramatically.
