Electrical gremlins at Surfers Paradise could force Garry Rogers Motorsport into an unscheduled test day prior to the Phillip Island 360.
The #33 Holden was the last classified finisher in both races having caused three of the total six Safety Car periods across Saturday and Sunday by stopping on the circuit.
As a result, McLaughlin is hoping that the team will be able to slot its last remaining test day for the season into the three week gap before Phillip Island.
“We're looking to see if we are able to get a test day in before Phillip Island,” McLaughlin told Speedcafe.com.
“It is one of those things that you want to have the car driving around and see if it has been solved.
“What stopped the car on Sunday was exactly the same thing that happened on Saturday. I came in and they wiggled with the wires a bit and then away it went and it never stopped again.
“We had a total engine change between qualifying and the race (on Sunday) but we think it might be something to do with the loom.
“It can't be anything else. We have just been troubleshooting everything when it is so intermittent it can happen at any time.”
Up until the first 102 lap race on Saturday, McLaughlin had shown strong pace, qualifying for Saturday's Top 10 Shootout on his Gold Coast 600 debut.
Adding to his frustration, he and Jack Perkins had made good progress from the back of the grid in race two before the gremlin struck again.
“The car was good. We started last and we managed to get half way through the field and we could have finished sixth,” added McLaughlin.
McLaughlin and Perkins finished 10th in the Pirtek Enduro Cup standings having taken eighth place finishes at both Sandown and Bathurst.
