    First of all I want to clear that I am not starting my locked topic " Loss of power".
    From last 1000 kms I am experiancing strange problem. Between 1600 to 1900 RPM.
    There is feeling of boost leakage deacceleration. This type of feeling is like automatic deacceleration even I hold throttle at fixed position while driving in 4th or 5th gear.

    What is "Boost Leakage Deacceleration"? Never heard this term before.

    First I read the title "Variation in power". I thought you were talking about "Variable" Geometry turbocharger behaviour across the engine rpm range.

    At fixed RPM torque varies even I don't make change in throttle position. Feeling of inflation and deflation is there. eg. You are cruising in 5th gear @2000 RPM. You are getting stable torque. Suddenly car starts to give variable torque. Just like clutch slippege. This situation repeats at random intervals

    Bhai,

    You maybe experiencing a variation in throttle on its own and not of your making. Is that what you mean.? I understand you have a problem, but if you invent new terms such as Boost Leakage Deacceleration", and inflation and deflation,. you could be confusing the engineer 100% at the service centre . The engineer is sure to make more repairs than amends, to satisfy your confused diagnosis and your constant woes would continue.

    It might be AC compressor cutting in or off.

    Bhai,

    This is your second punto rit? earlier you had a FGT with had some issues due to bad fuel.its strange that the 90HP also started showing problems. Please ask some one else to drive it and ask them if they feel anything unusual.

    Bhai, please take your car to the service center and have some Fiat engineer test it and post the observations here.
