So i noticed it after i put my N75 in. At higher RPM's while the boost is dropping off it actually starts twitching. Twitching like crazy actually. any clue what this is about?

no misfires. the boost is actually twitching, as it gets to around 15 just starts jumping between like 9 and 15 like crazy

sounds like surging, maybe your car doesn't like the n75h valve.
