WRX 06 stage 2

hello guys.

I am new to the forum. I have a wrx tr 2006 US specs.

I have recently installed a full 3" invidia TBE with catless DP and running on cobb stage 2 map. The turbo is TD04 stock. I am overboosting on 4th and 5th gear on high RPM. I know that my only solution is to pore the internal wastegate of my turbo or install an EWG. I am willing to go with the EWG since my future mod will be a VF48. I just want to know is it normal to overboost on a TD04? What do I need to install an EWG? grimmspeed uppie and tial 38mm is all what I need? Thanks.

the RIOT act is more helpful than not
The catless DP could be the cause of your spikes. And the OTS map isn't helping matters any either.

I'm not to savvy on wastegates though. Hopefully someone can fill in my blanks for you about the wastegate options.

I also have a 06 on the stock td04 with tbe. I was also overboosting on the cobb ots map. I went ewg and it solved all my problems. You will need uppipe, wastegate with all springs, a tune, dumptube, and a 3 port ebcs is recomended.
