I'm looking at an Amarok purchase and don't mind the TSI at all looking at the numbers. Haven't been able to get behind the wheel of one as there's not many around but I'm looking at the tuning scope of these... Would there be anyone in Melbourne that would be able to set it up with a catless dp, tune etc? Has anyone driven them back to back with a diesel? Just concerned about it being able to move ok down low too.
