    040 fuel pump and new 3" down pipe and exhaust car is now running better than ever but in a 3rd gear pull hits now and then 1.7 bar then drops to firm 1.5 bar, in 4th gear pull only reach 1.55 max . then surging up to 1.6 to 1.7 . no boost leaks on turbo side
    or vac side , new n75 and forge valve. i will vag com this weekend to check for error
