Thanks for the input. Just picked up the prl intake and waiting for the Prl front pipe and down pipe to be availableStart with picking up a KTuner. Run the basemaps. If you are still wanting, Purchase the TSP Stage 1 or Phearable tune (no god mode).
Both OTS tunes will support bolt ons.
Custom tune if going beyond the basics, bigger turbo, etc.
Don’t waste your money on a custom tune on a stock car.
I agree with list. Another thing I would add is the hasport rmm, wheels and tires for 2019 si on down and lowering the car last.1. Tuning device
2. Intercooler or cold air intake
3. whichever you didn’t buy in #2
4. Handling mods - lower springs/coil-overs
5. Wheels and tires
6. Exhaust
