I did some VAGCOM logging in 4th gear a few weeks ago on my 1999 S3 (APY - 210bhp, 270 Nm). The max torque figure I got was 267.5 NM. I did some more logging in VAGCOM tonight and the max torque I am getting is 248.5 NM (I did two runs, just to be sure). The figures for my MAF are the same for both - a max of 165 g/s. The car feels more sluggish than it did a few weeks ago. Doesn't feel as lively and responsive, if that makes sense. Especially at low revs. What would cause my torque figures to drop down by 20 NM?
