I've just upgraded my '01 9/5 Aero auto with Abbott ECU,backbox and filter.
I've not had much chance to really try out the new performance yet but it certainly seems quicker than before, with sustained pull in the midrange.
One thing I'm puzzled about is that it doesn't boost into the red like my old Abbottised 9000 Aero used to. Giles at Abbott assures me that this is quite normal.
I'm curious to know if those with the Speedparts Stage 1 upgrade see a change in the max boost level pre and post upgrade. Both companies claim much the same power increase - perhaps its just different ways of getting to the same end?
Would appreciate any feedback.
