The tuning wizards at Superchips have released details of what they can do for your Vauxhall Astra VXR or Opel Astra OPC as we know it.
Already producing a healthy 206 kW (280 hp) and 400 Nm of torque from its turbocharged 2.0-litre engine in stock guise, Superchips’ Stage 1 option relies on remapped ECU software resulting in an additional 17 kW (23 hp) and 61 Nm along with a crisper throttle response. Owners can either perform the change themselves with a Bluefin ‘Plug-In and Go’ DIY programming handset or make an appointment with their local Superchips dealer. Pricing is £455.
Stage 2 costs the same, but is only carried out on cars fitted with a free-flowing exhaust system and sports catalyst (sold separately through Superchips’ partner Thorney Motorsport for £1,614). Those alterations see output raised by 24 kW (32 hp) and 75 Nm.
