I'm running a 2010 v6 with 272 bhp ATM. Mods I'm running:
Sct tuner at 93 octane tune
Magnaflow dual exhaust kit
Jlt cold air intake
Pypes shorty header.
Overall costed around 1200 but totally worth it. If you want to go faster than that though I'd suggest just trading the car in cause a good turbo/super charger is around 3-6k$
