Newby questions...

Have had my 15' ST a few months and love it but a couple questions. Bought it from a Ford dealer and did the test drive but with the salesman with me and the neighborhood we were in I couldn't really open it up. But drives perfect. Had it delivered and once I got it out on the highway, it has a blow off valve which does sound cool, no problem. So can one just install an upgrade on the blow off valve or does it have to be with a larger turbo only? It pulls strong but I can't compare it to a stock one.
It was also lowered with H&R springs but it doesn't make U-turns so great. Is that because of the lowering springs? Thanks y'all...

Sounds like you’ve got a great ride! Let’s break it down:

Blow-off Valve

You can definitely upgrade the blow-off valve (BOV) without upgrading the turbo. Many enthusiasts do this for better sound, durability, and quicker response. An aftermarket BOV can help even with a stock turbo, though it won’t necessarily add power—just refine the driving experience. If you plan to upgrade the turbo in the future, look for a BOV compatible with both setups to save money down the line.

Lowering Springs and U-Turns

The H&R lowering springs are likely the culprit for the reduced U-turn performance. Lowering a car often reduces suspension travel and changes the steering geometry, which can make tight maneuvers trickier. If it’s a big issue, you might consider adjustable coilovers to fine-tune the setup or upgrade the sway bars for better balance.
