I've got a new-to-me 95,000 mile 2015 SR5 (replaced my 4th gen V8, totaled in a wreck unfortunately), maintenance records show regular maintenance and there are no known issues. We live in Colorado Springs and drive through the mountains regularly. I miss the V8 and am considering adding a supercharger (Magnuson or Procharger), but most folks on the board who did the mod installed them on relatively new vehicles. Anyone see any issues with putting one on a vehicle nearing 100,000? Opinions wanted!
