The car in question is a peugeot 307 1.6 16v tu5jp4 with ME7.4.
The car has allways felt sluggish and consumes a lot of fuel imho...
Theres also a whistling sound coming from the engine bay, which gets louder as revs go up.
Also throws a depo fault and I allready changed the cat.

So I'm guessing
RPM
IQ
IGNITION ADVANCE
MAP
TPS
and Lambdas???

Anything else?
How would I go about logging it?
Just 3rd gear WOT?
