Hey guys, so my 2018 Sti has a invidia Catless DP and Cat back exhaust. What stage map is appropriate for these mods? My car recently got a P0244 code so I’m not sure if that’s because I’m running at cat less DP without having any sort of tune on the car.

You need to have the car professionally tuned to run a catless down pipe. Modding an sti without the proper tune is recipe for disaster. This has been covered heavily over the years, please take a look and you'll find plenty of info about this. I recommend you get yourself a Cobb Accessport and contact a tuner to set up a protune or an e-tune.

As for the code, well what did the code say?

The code said “Turbo Wastegate solenoid A range/performance“. I’m guessing this is an over boost code?

Yes most likely due to an overboost. I would recommend taking it easy on it until you get the correct tune on the car. Be aware that boost creep is a real possibility, especially in the cold temps.
