Evap valve won't be the problem as it's closed in boost. What specified / actual parameter was logged there? Boost?
The most useful things to log are:
Boost - specified and actual
Fuel Rail pressure - specified and actual
Low pressure pump duty % - Shouldn't exceed 55-60% usually.
Throttle position
Lambda regulator
Knock regulator
MAF
You need to find a quiet road and do a full throttle pull to the redline in 4th gear. May need to do that at 3 in the morning!
The longer you can keep the pedal pinned, the better, as it will show how closely the requested and actuals match and their responsiveness.
From a nuts and bolts perspective, the usual suspects are: leaking boost pipe O rings, injector(s) going bad, vacuum leaks, high or low pressure fuelling deficiency, worn spark plugs, coil(s) going bad.
And less commonly, a terrible remap can cause problems. Is the car standard or mapped?
