recently got a new car,and I've been reading the manual..
recommendation is that tyres are at 39PSI for maximum economy ( Compared to a normal pressure of 35 PSI )
I'm shocked at how poor the car now handles before it cornered likeit was on rails, Now feels very skittish as if it wants to slide.
anyone else had this sort of experience

it would be handy to know what car it is.

Yes, that's exactly what you'd expect, and why they've given you the choice, dependent upon your use and roads. Normal pressure - the tyres can flex a bit over bumps and in cornering, so will grip and ride better, but that flex takes a bit more energy to roll. Higher pressure - less flex means less grip, but lower rolling resistance. So drop down to the "normal" pressure, for your kind of use on your kind of roads. The higher "eco" pressure will be less of a compromise on smooth, straight roads - if you do mostly motorway cruising. Low-rolling-resistance "eco" tyres give a similar change of focus compared to more performance-focussed tyres, with the difference there being in the rubber compound and construction, rather than the pressure.

The 'eco' setting will also give a bumpier ride and the centre of the tyres will wear faster. There's a trade off between fuel economy, comfort, safety & tyre wear. As Adrian said, the consumer is given a choice. Personally, I would prioritize safety.

I've always used Eco pressure in the past with nonoticeable effect on handling,this is different so will be lowered back down

Just keep reducing the pressure by 1' until you are happy with the handling. You may find at 37' the handling is fine
