He told me that he was getting almost no boost up till about 4k rpms and then it build boost. This tells me that he only has boost creep. If the wastegate was stuck he would have built boost before that. So its only boosting once he starts flowing more air than his system can handle.

The only way to fix is either port everything and get a bigger flapper, or like he said he might do, sell the turbo, get a new one with a better flapper, and a new o2 housing

 

As of right now, im just gunna get my turbo ported by ams and have them install a new 34mm flapper, which they quoted me at 200 bucks, which IMO isn't too bad. So I will prolly be sending it out next week for that. Im also going to scrap the sh**ty custom exhaust and get a downpipe and catback from megan, and also an external dump o2 housing

 

does this sound right to anyone else, that that's my problem?
