    Default Suzuki Cultus EFI engine losing power..:/?

    i have cultus 2007 VXLi since start nd has clocked about 135k kms....Landirenzo CNG kit was installed after around 20k kms..!..completely maintained from Mini motors..
    so here is the problem...until 120k kms..had no problem in accelerating it 120 on motorway with 5 people sitting on CNG...reached 120 slowly but it did nd on petrol, 120 was a piece of cake but now even with one person on board... after like half hour of full acceleration it just doesn't cross 110 nd even on petrol it goes upto 120 max nd wo bhi rou rou kay that tooo in 4th gear....as soon u shift to 5th gear..speeed starts decreasing...:X.....!!..what might be the problem ?...
    oh nd jerks are also felt on high speed especially on CNG..!

    no sign of engine weakness though..
    mobil oil was full after 5k kms...
    it wasn't black..!
    no smoke of any kind..!

    here are few things recently done..:
    tuning twice from mini motors in last 5k kms from different people..!
    changed plug wires to genuine sumitomo ones..!
    using genuine NGK plugs bought from Mini motors..!
    have used injector cleaner..!
    changed mobil oil..!

    You answered your own query. Tuning from FIVEEEE DIFFERENT PEOPLE????? Also, chances are that the injector cleaner loosened the debris in the fuel tank, lines, filter and ultimately clogged em. Wonder what would be the condition of plugs and air filter??

    tuning done only twice bhai from different mechanic of the same workshop nd both are most senior personals in that workshop..!.ur theory abt injector cleaner might explain the fact abt petrol performance but what abt CNG..?...air filter changed to Suzuki's genuine one...plugs changed at last tuning..!
