It usually only $200-500 for a dyno tune and street tune.$1500+ just on tuning.....they took you for a ride.
But yes tuning is everything.Im sure with just bolt-ons,bigger injectors,and a few more lbs youll be more than happy.
Turbo cars make power so easy its not fair to us non-turboed 4cyls.
Ohhhhh,big ballin right therereaon being I kept adding stuff and getting re tuned...initial tune was 600....also I flew out the tuner that worked on my car...
