Hi, Im noob obviously. Just had my new HKS exhaust system and HKS intake recently, should I get a tune or ecu reflash? What is the different ? And do I need a boost controller? Need help here.....thanks
The stock unit is incapable of consistently controlling higher levels of boost. Hence why you need a boost controller of some sort to help keep more control of that air. The tune is whats used to set the PSI.
You guys are correct, you dont need a boost controller but a 3 port is a good addition. Really alows the tuner to manage boost throughout the rpm range. In my case i found the boost to come on strong and hold to red line.
