Just as a note of caution, don’t think that because the shop or products like OTR has a Walkinshaw badge on it that automatically signifies an agreement by Walkinshaw to warrant the driveline in lieu of replacing the factory tune (which voids your Holden driveline warranty).
Objectively the value of a Walkinshaw brand or sticker on a VCM intake is not worth paying a higher price at all. Most any place will do OTR and tune for that price, maybe full custom tune half a day.
My understanding is the three year conditional insurance premium you pay up front to cover potential issues with the driveline that is void through Holden is only included with a qualified Walkinshaw “power pack”. Not with an OTR and flash tune from a franchisee.
Although the front desk will blissfully let you believe because golden umbrella marketing brand is
of course the one and only friendly expert magnanimous warranty god, ask to see the applicable written contract and ask the manager to initial that before you pay more than $1000 for an OTR and flash tune.
