After reading a thread about turbo replacement in this forum i began to do my own tests with my beauty as i faced somewhat a similar issue. here is the story.. I own a 75PS punto and according to the docs turbo should kick in at about 1700-1800 rpm. But in my case I cant feel the turbo hitting me always. This is especially true when i Gradually accelerate to and beyond 1700rpm. If i drive with a light foot I"ve noticed that i cannot feel the turbo at all even when i take the rpm to 2000,2200rpm there is still no feel and then its time to change gears. in 2nd gear i dont feel anything in 3rd gear sometimes i feel it. There are ocassions where even when i drive with a heavy foot i cannot feel the turbo boost very well. This is now concerning me a lot. WIth Full load and AC on i can feel the turbo hit but even that is not always. With just me driving i sometimes feel the turbo working and sometimes dont. I dont know if the boost is controlled by the ECU that it opens it up when there is heavy load and does not do so under light loads. Please advice. Also my car is a '09 Dec model .. In the extended warranty booklet i see that "Turbo" is mentioned so now i would like to know if this is a issue with turbo or could there be a leak of some sort. If anyone is residing in blr and doesn't mind meeting me I would like them to TD my car and see if my claims are valid.... It would be really helpful guys ---------- Post added at 09:18 AM ---------- Previous post was at 09:13 AM ---------- I'm not sure if i should suspect bad fuel.. Also my 3rd service is also just over in Dec '11 so air/fuel filters must have been replaced. If in case its a story of bad fuel (I use BP in tyagaraja nagar always) what should i do?
