Aftermarket RPM meter problem

hiya guys.
I have a small problem with my Rpm Meter . ITS installed in my 2005 Alto VXR (1000cc).Well the problem is that the rpm needle is a bit slow . i mean when you push the accelerator on neutral . the engine races i.e the engine sound gets louder but it takes about 4-5 seconds for the rpm to rises.the same occurs when you remove your foot from the pedal.
Why is this So ??
And how could i fix it up??

Check at the back of the tacho for a switch that switches impedence usually to alow operation with a particular number of cylinders. Its marked 3,4,6 on most tachos. Most probably thats what is causing a faulty reading.
