3.3TT Full Catless and Tune.

[ClayGray98]

I've tried looking for a clear answer to this question of mine, so I figured I'd hit up the Forum experts. I currently have BMS Intakes, Catless Secondaries, X Pipe W/ Resonator Delete and Muffler Delete. I want to get the Catless Primaries, my main question is, would a JB4 suffice as far as a tune for proper Air/Fuel ratio and correcting Overbooked, or would I need a Full Dyno Tune? Thank You in Advance

You could get jb4 yes but you need ewg for overboost to be minimized. It can still happen though. You may need to tune on it also to tweak waste gate settings. You'll also get a check engine light that will limp the car. There's isnt a massive gain from primary delete. Imo just hold off or go high flow cat that for sure won't throw a light (some high flows will)

Thank You for the response, I mainly wanted the sound, just like my Long Tubes on my Coyote. I might have to skip this until I get a Proper Dyno tune. Anybody in So Cal know a Reputable shop to install Catless Primaries and Tune the Stinger?
