I didn't have such a great experience with sending my ECU to ECS- East Coast Supercharging. I had a perfect running 08Z and sent my ECU to them to have a simple tune cause I just added headers. ECU now installed and am getting Idle hang between shifts that were not there before. I'm also getting intermittent codes, HVAC lost communication, service traction control and service electronic system. these codes are very intermittent and come and go. Not so much an upgrade, now I'm about to take it to a tuner to fix.

So tune will yield you about an extra 20HP, but once you de-hobbling what the TM is doing, the difference in seat of the pants is eye opening instead.
As for the next step, that is throttle remapping, and if taken too linear of a relationship between the gas pedal and the throttle body, can make the car almost un-drivable in a novice hands isntead.
So bottom line, just de-socker mom the car to begin with with just a re-tune, and see if you still feel like you still need more HP next for street use of the car.
