it is likely you will see inprovemnts from mild cam inprovments
but it is just as likely that you will loose drivability
and make the car run like a bag

perhaps you sould look at a ecu been your first preformance improvment

VVT is on the intake campully... so if you change them you loose it... vvt changes the timming by 15degrees(from memory) so you could ether set the adjustable intake to be fwd 15 and have a bouncy/shit idle (also make sure not to rev it to high while cold) and if you have them set with standard timming the engine prolly wont want to rev near as hard, your better off putting a switch on the VVT an making sure everything is tuned up well... unless you can afford new cams... but as vvega said.... look at the ecu... some improvments can be made there.

blacktops as we all know run map sensors so any change in manifold vacumm at idle or light throttle which you will get if you change cam timing will cause it to run rich (less manifold vacumm), so short answer would be to change you ecu first
