Hey guys, since doing my TT conversion i've noticed the zed doesn't pull very well in the high RPM range(5500+rpm). I've driven many many variants(auto/man etc) but none have nosed over as bad as mine up top. The car pulls like a train to 5000rpm and then its almost as if its an NA after that. Boost holds a steady 12PSI from 2800-7000rpm. I'm planning tomorrow: Drop the exhaust + check for collapsed cats/mufflers Change fuel filter Try different fuel pump Inspect FMIC and all pipes/hoses/clamps Fix all possible boost leaks More details: Base timing is 15* Auto VG30DETT with manual turbos 2.5" AMS Turbo inlets Boost is at 12PSI Compression test had good results On its last hard run ECUtalk showed 98% IDC and 4.535v AFM. Any idea's on what else to check?
