I'm reasonably confident if I posted my GTI for sale with a "Modified engine" and it had a bigger turbo, meth inj, custom ecu, modified fueling, bigger exhaust, intake, etc., I'd be dragged hard for making a misleading ad since the engine is stock.Not argued...
Just the video title & the way they go on about "stock engine" is soo click baity.......
Personally "stock engine" should mean as it came from the factory.....not a different engine, bigger custom turbo, methanol injection, custom ECU, modified fuelling, bigger modified VWRacingline exhaust, forge air intake, etc., etc..
