So i just got my 03 civic ex back from the dyno shop after adding my TSI turbo kit with the AEM FIC and getting it dyno tuned, and i'm pretty upset with the halfassed tune they did. For some reason every once in a while when im driving it around it starts acting like its boggin down and about to die jerking violently the more you presss the gass. Then all the sudden it goes away and wont do it again for the rest of the day or sometimes it will but its just random and its rare but i'm pretty sure that **** aint normal if it happens at all. The guy from the shop said that my wastegate lets boost creep all the way to 10.5 psi at some rpm points even though its set to 7psi, so i was thinking it probably is caused by the boost creeping over 10 and trips out the map? Sorry for the paragraph but i just wanna have this build done right.

Well I believe your waste gate is controlled by a spring so replace that and see what happens. If its not mechanical, and if it's an electrical problem, that's more of a hassle
