Ok so I have a 91 tt with 109k miles on it. Car bogs down at full throttle and the exhaust sounds muddy like poor ignition. At 3/4 throttle it pulls much harder, but still sounds muddy.
Notes:
Compression test shows ~150psi on all cylinders Idles smooth without any shaking Turbos make 9psi Can smell unburnt fuel from exhaust after a pull Ran on Dyno yesterday and only made 170rwhp :-( Injectors should be stock (car was recently purchased so I don't know for sure) ECU is stock Base timing is correct Pulled coil wires individually and there was a noted misfire for each cylinder so I'm assuming I'm firing on all cylinders when they are all connected.
Only thing I can tell done to the car was aftermarket mufflers. Exhaust looks stock otherwise. Also has a pop charger.
Kinda stumped here.
