hi now my rear tyre pressure is 33 and that of front is 35.drive is now smooth when we got delivery they did nt even check the pressure the drive was very rough now its smooth and anti rust paint has decreased ambient noise and no stock pressure was 50

Its common with all Maruti dealerships. Most cars delivered by them have the tyres setup at around 40 psi or around that range.
Tushar,
tire pressure is to be arrived at by trial and error. You diesel has a heavier engine, so front tire pressures will be higher. In my Vxi, I used to keep the pressure at 33psi as suggested by the dealer initially. The ride used to be thrashy always. Then I noticed that the drive used to softer just before I would fill air back in. The tire pressure would usually be 31 or 32 psi at that time, so I began to maintain that pressure and the ride improved considerably. After I fitted alloy wheels, the fellow did nitrogen filling at 33psi but I found that actual pressure was 36 or so and ride was rough again. So I bled some nitrogen and the car has become softer again. You will need to try out +/- 1 or 2 psi for yourself.
By the way, in first service, all they do is wash the car and check the fluids. Around the time mine was done, I was wondering why they wouldn't change the oil. But the dip stick revealed very clean oil, so I persisted with it
One good thing I noticed in the last few days is that low speed braking has improved a bit. You can now feel the deceleration. I also just fitted a K&N filter instead of the stock and the car revs more happily now. Just had it for a couple of days so will give a more detailed report a bit later
Anyone knows whether the Swift comes with semi-synthetic oil or synthetic oil from the factory? Meaning, do I replace it at final free service or change it at 2nd service?

did you check ideal rpm

idle rpm is around 750 and ameyam oil is changed on 3rd service advisor said synthetic oil price is 3600rs. and does k and n increase your idle rpm my vxi struggles in first gear without acceleration and what is the price of this filter thanks
told them to check ecm settings .when i was in MASC for servicing my alto a new swift customer complaining about same thing (didnt remember that it was ldi or vxi)then MASC make some changes with ecu then big boom customer is happy with pickup in first gear

it would be diesel then and it has good low end torque
K&n just adds a bit or free acceleration
If your idle is too low, you can ask them to increase your idle. But with the low end torque of a diesel you shouldn't have that issue. May be you need to get more used to the car

K&N and similar filter by design allow more air to be sucked into the engine by efficient filtering. It does make the engine peppy and free revving. However, for a more pronounced low end torque you should go for a FFE (Free Flow Exhaust) with custom headers. There are may shops in and around Delhi NCR which takes care of the same. Diesel by default has a pretty good low end torque, its the high end of the rpm range that you would find the diesel lacking. Petrol lacks the low end torque, but makes up with good torque at high end, hence FFE tuned for low end torque would make more sense in a Petrol. Additionally you could go in for ECU remapping. FFE and ECU remapping are costly affairs and could set you back by approx 12-30k INR.
I guess most maruti engines now come with Synthetic oil, atleast my 2012 Swift VDi did come with it from the factory, hence the prolonged oil change interval. For mineral oils its advisable to change them at 1000km or first service.

can i just install k and n for rev and what is its cost and factory engil oil is not synthetic and it will be changed on 3rd service not on 1000 advisor said
K&N has two options, one a replacement for factory filter (Its the same size as the factory filter and drops directly and fits perfectly in to the filter box), the other is conical air filters (you might need to remove your filter box for fitting the same, else you would have to route your plumbing to go to the K&N rather than the factory filter box). The conical air filters would expose the filter to the elements but would provide a much better breathing engine. The factory replacement filters are cheaper compared to the conical ones (since you would have to re-route your plumbing and build custom holders for the same). They start at 3.5-4k. Do read reviews as well as drawbacks of each before jumping on the K&N brandwagon. Also, these filters needs to be cleaned at regular intervals with special oils for them to last thier lifetimes. You might need a replacement while its being cleaned. My car hasn't had a day off since I bought it.
I for one would rather stick with the manufacturer recommended filter rather than K&N since they are dirt cheap and you could replace them at 5k km interval easily with just a couple of tools. Also while commuting between work and home sometimes I do encounter waterlogged roads (upto half my tyre height), which would certainly cause a K&N conical to ingest water(hence I iterate that the placement and your travel need for the same needs to be kept in mind while designing the plumbing).

i will not be able to do any modification for conical i would go with simple one which can replace stock filter but will there be any difference in rev and fuel economy
You would see a marginal improvement on rpm, since the car ingest air more freely. However, improvement on fuel economy is subject to your driving style. If you are drive enthusiastically, then no improvement would show, however on careful driving, you would see some improvements although its would again be marginal.

can you tell me the model number and can i fit it on my own and does it void warranty or does it create any changes in ecu
