    Downpipes really opens up exhaust and turbo spools way quicker. Big difference

    Sorry I was not clear I’m talking about primary down pipe like lap 3 and NGT performance. I have the JB4 and the Ssr secondary down pipe. Looking to change the primary to open her a bit more but I was told it get to limp mode.

    I'm running full turbo back, catless primary and secondary with JB4. To prevent codes you need to use the passive delete feature on the wmi settings page. To do that in US you have to use a vpn app to connect to Canada IP, then set country in jB4 to Canada. Because jb4 is CARB approved for various models they cannot have emissions defeating features in US.

    Besides the codes do you have overboosting issues?

    Also why dont you just hook up a O2 sensor spoofer on the downpipes?

    Overboost only happens occasionally when boost target and boost actual vary too much on lower maps in the cold air. A Given WGDC is making more boost catless so the difference between target actual is greater than normal. The solution is simply to run a higher map. I daily on map 3 and don't have any issues. I also have to still add IAT wire when should also add more commanded ECU boost and should address the issue as well, but its been too cold for testing. Once eWG is added to JB4 this will not be a probably at all on any maps or temps.

    The IAT cable is is really simple. Took me 10 seconds. You need to go in and set 6Cyl to 20 (at least for chicagoland weather ( -3 tomorrow -_- )
