Well recently I have done a few mods to my car and everything was running fine. I added an intake and a MBC. I was running right around 20 pounds for a few days and everything was all good. Then a few days ago I would hit 20 pounds and about 4-5 grand just drop off to 15. Then 2 days ago I could not boost more then 12 pounds. Now it will just boost up to about 15-16 and drop off to 10. So far I checked just about everything that I thought it could be. All vaccum lines are on and all the hardpipes are on and clamped down. So my next step was thinking that it was the boost controller, took it off put a friends on and it still does the same thing. The next thing I thought was that it could be the ****ty stock bov. So I take that off put on my buddies greddy type-s and try it out with that, same results. Now I am starting to get a little pissed off and wondering what the hell it could possibly be. The only thing that I am thinking is maybe is the intercooler pipes with all that rubber leaking somewhere or if its not that could the stock intercooler be ****ed up and maybe I blew a weld somewhere? Also I checked the nipple on my wastegate to make sure the hose was still on and everything is fine. Yes, Yes I know my car is a mitsubishi so if thats all your going to say please refrain from doing so.

 

Your car is a mitsushitty

You added an intake?? You mean like a new filter? Cause last time I checked turbo cars dont have a normal intake pipe... Also If it is dropping it off, its a leak like your thinking, so check that first, if not that my next guess is that you some how blew your turbo.

 

Yes I meant a new filter, sorry I didn't clarify that. Also I'm 100% sure that its not the turbo. I unplugged the hose to the wastegate yesterday and ran up to 30 pounds very easily, the turbo spools up very nicely.
