Catless dp

I am wondering what else I can do with the M271EVO engine, I am looking for a better intake but haven’t seen any worth it. Honestly thought of custom making one. Anyways, 230bhp on stage 1 and 260 stage 2 is what I know is possible but what happens after that. Is there any internal work I can do like cams or something idk I haven’t spent a bunch so far
thanks

 

I have one from Tornado Tuning but I opted for the intake pipe and kept the stock airbox. I find my car tends to lose low end with cone filters and my catless DP.

 

Couple of things
1. Larger Intercooler
2. Aluminum charge pipe
3. Hybrid Turbo
4. Camshaft Upgrade
