Thread: top swap pulley ?

unless i see knock and the car starting to run lean up top, then i would never swap injectors. this is why EVERYONE needs to run a wideband on any car they want to make power with.

Definitely agree with the wideband.

Had I been running one earlier in my ownership I'd likely still have my modded TSi Talon.

Running lean at 6000 rpm and 125 mph makes for bad things to happen to pistons and rings.
