So I got my turbo-back exhaust, and intake system done recently and that's stage 2 in the Cobb AP. To get to stage 3, an EBCS is required. Now if I put in an EBCS, would the Cobb AP still tune it to where it won't overboost OR do I have to go get a pro Tune? Thank you in advance for your help.

 

The stage 3 will make it driveable, but a protune is highly recommended

 

You don't need a tune to go to stage 3, but if you want the max out of your mods then a protune is where you want to go with. Just remember to do the recalibration for your intake with stage 3.

 

The Stage 3 map is designed to work correctly with the COBB 3-port, so you should not have any overboosting issues. The 3-port makes quite a big difference on these cars and is pretty inexpensive for the performance you get.
