I wouldn't worry too much until you change the intake as well - once you upgrade the intake then you will need a seriously different tune given that you have also done the exhaust. the issue is not just the tune but also opening up the secondary butterfly's to 100%, removing the 1st and 2nd gear ignition retardation and lets not forget the speed limiter and the cooling fan switching temp. If you screw with it now - you will only need to do it all over again when you do the intake upgrade.
Just my 2 cents.
