I'm new to the whole Evo scene, so I gotta ask this question since I can't find an answer.

I had an SRT-4 previous to my Evo, and how I solved boost dropping off at higher RPM's was to get an adjustable wastegate. That solved my drop off problem and I held boost all the way to redline.

Is there such a mod for the Evo? I'd like to hold my boost all the way.

 

get a boost controller.. pref electric..

 

I have a Profec B Spec II that I had from my SRT...that alone will cure the boost dropoff?

And what's a safe boost level for the stock injectors?

 

20-21.. no more.. and run at least 93 octane..

 

Well that's going to suck since Wichita has no 93 octane. Guess I'm staying stock boost then.
