Hi, I am from Kuwait and I own an 09 EVO X SST. I installed 3 upgrades a testpipe, dropin airflter and a down pipe. The car is running fine. But I want to raise my boost can i remove the pills from the boost tube?Will it cause knocking? or should i install a MBC? Can the SST endure it?
I did some research and what I understood is that it is Ok without Tunning.
Help is much appreciated.
Thank you.
