I'd go for REVO if you want aggression
Remapped GTi is quicker than a Standard ED30/Pirelli... BUT the ED30/Pirelli have a bigger turbo than the GTi ( KO4 ) which gives huge potential for remapping
Remapped GTi i'd expect 250bhp - potential for 270bhp ( with exhaust and further stages )
Remapped Ed30/Pirelli 300bhp - potential for 360bhp ( with exhaust and further stages etc... )
Certainly puts the R32 in the shade... but i just love the sound of that thing !
