For $2.5K there better be a dyno report showing a miracle. On a stock motor, stock turbos and stock fueling a custom 93 full-kill tune gets you about 550WHP. That price can't include HPFP upgrades. I'm suspicious...
I would suggest a custom Paul or Cary BM3 tune and save $1500 for new fatter rear wheels and drag tires.
