Next month i will be finally getting the tune for me car. I talked to my tunner and he says i have a choice between open ecu and ecutek flash. Theres about a couple hundred dollar difference between the two, and i was wondering which is better? I want more power and something that will be great for a daily driver too.

 

If your sig is all the mods your running then just do a open

might want to get a 3 port boost solenoid too

Enjoy

 

what does the 3 port boost solenoid do?

 

I would say def go with open source. I don't think there are really any advantages to running ECU-Tek as opposed to running open source.

 

A 3-port pneumatic solenoid allows interrupt or blocking of the boost pressure rather than just bleed type control.
