I've noticed lately at 100% throttle, the acceleration feels a little jerky.
I've done some logging... here you can see where I floor it (white line in top graph)... the boost comes on fairly quickly (green in top graph), and the rpm and engine load climb (top graph) - however the engine load seems to stutter a bit at the time of hitting full boost.
VVT right/left seem fairly well aligned (middle graph) and learned ignition timing I think is acceptable?
Injector pulse width goes a bit strange as full boost is coming on... and the MAF sensor has a few dips in it in roughly the same spots as the dips in the engine load.
I've not done much diagnostic logging before... does anyone want to take a stab at what might be the problem? Slight boost leak somewhere at high boost? Blocked injectors?
Thanks in advance for any help
