So I recently bought a 2003 evo 8.
I dont feel it should perform how it is..
The car sort of struggles to go past 6000rpm while driving and it starts hopping..
The boost gauge hisses while boosting and I can also hear some hissing sound on the intake manifold.. I blocked the hole to the boost gauge,, what hose is that behind the intake manifold? and any tips on stuff I can troubleshoot? Diagnosis brings no trouble code.

Sounds like the typical boost leak symptoms. Get yourself a boost leak tester and go from there, simple to do.

is your car tuned first check for boost leak if there is no boost leak you should get your car tuned and it should fix the problem
