turbo spool not as hard

alibaba222 · 02-15-2015, 05:52 PM

whats up guys,
so i got a 135i that i just installed a jb4, afe intake and a charge pipe with a tial b.o.v.
i just noticed that in 1st thru 3rd gear at around 50% throttle the turbo spool is pretty loud until i get to about 3700 rpm and the noise just dies out, i can still hear it spool but instead of it getting louder or staying the same it just dies, it also doesnt pull as hard when that happens, almost like if one of the turbos just stopped spooling.

there are no code or smoke or any weird sounds, could it be the turbos going out??

Best bet would be to datalog during a pull and post up the excel file so we can take a look at it. Then we would be able to see what's happening.
