What kind of boost gauge? Was it hooked up correctly? Wastegate boost is around 12 psi. Stock should be 19 as mentioned before.

I see you're living up to your signature. How in the hell can you not know this utterly basic piece of information? This same question has been asked HUNDREDS AND HUNDREDS of timeS!!! It's also listed on the Mitsubishi website in the specs for the Evo!!! Unbelievable...freakin teenage punk kids always wanting to be spoonfed.

No surprise you're running base wastegate pressure on a used Evo with just an intake and no tune. Nice work there!

Do you have a boost controller? If so check to make sure its installed correctly. If not check all your boost hoses. It sounds like you're running wastegate pressure.

Agreed, but not helpful in the least. Flame away, I don't care, but at least give the kid something constructive.

why would I do that? I've answered the question probably 20-30 times already. What you're suggesting is that I spoonfeed him and REWARD him for blatantly breaking the rules and not finding the damn answer himself with a 2-minute search. Sorry, I prefer not to perpetuate idiocy and laziness.

I guess I could have done what you did and just respond to someone else in the thread and not provide any help either, yah?

Notice I said "something constructive" I'm not suggesting that you give him the answer and walk away, although that is the fastest resolution. Keeping in mind this is an internet forum and the same basic questions will be repeated time and time again, why not post a link to a search that might be helpful to him? You are then training the newbs to promote the behavior that you would obviously prefer. I'm not sure that your unhelpful reply and my slightly off topic reply are quite comparable.
