Afternoon chaps.
While reading the 2.2 hesitation thread, I picked up the following website:
Powertrain Performance Graph for Alfa Romeo 156 JTS -02 (122 kW)
This seems to show the 2.0 JTS engine's BHP at around what Alfa state at 164. Having looked at the readings for the GTA they are spot on also at 250.
We have seen the threads where the red dot's (amongst others) readings were way down at around 140 for the 2.0 JTS engines.
Any ideas on why the differences in readings? One thing I don't know is whether the JTS is standard.
