2010 Alto Idle RPM

Hi Guys,

Anyone has any idea why 2010 CNG Alto's idle RPM might increase after driving it for about 20-25 minutes?
Is there anything inside the car that controls the RPM (really naive user here) coz sometimes (mostly when running on petrol) the idle RPM comes down to normal speed but on CNG it doesn't. I got it's first service recently and the guy reduced the idl RPM but it jumped up again after driving it for about 5 minutes. I'm concerned this might affect the mileage of the car.
Should I be concerned? Should I be breathing down the service center's neck?

its normal .... in my city RPM stays at 500-600 on petrol but when car comes to CNG it jumps to 800-900. But it transferred to gas it must be stable it must not fluctuate fficeffice" />
