Still no confirmation on EPROM mods yes/no for ur-q IA Stage II, but, in Ned's defence, his ads do not claim any EPROM, PROM or CHIP changes or upgrades, just "Audi Engine Computer Modifications." So I don't put this in the same class as Supershits and TcrAP mods that *do* claim "CHIP" and "ERPOM" upgrades...... -bob
