When I put my foot down on the gas heavy there is a squeal at about 60km any ideas what it could be ?

If your air conditioning is on, it's quite possibly the belt slipping.
Mine does it when I'm accelerating hard and the auto box shifts gears. But without AC on, it never happens.

It's your tyres man with all the extra power the pod filter is making

Yeah with my airconditioning on it does it
And very funny haha :)

Yeah AC belt, replacements can be found for around $30 locally.

Are they easy to change :)
