Why wait, stage II is only £50 plus VAT upgrade on stage I if you use REVO. Even if you go straight to stage II you still pay stage I plus the upgrade so overall it's the same price.
But I want: Complete Milltek TBE + (Forge) Intake + APR fuel pump + (Forge) Intercooler + Forge DV + REVO 2 Map all in one go.
