Hi guys,
This is my second thread on here (woo!)
I need some information & that's why I am posting here. Last time I did & got tons of help! I am hoping for same again! ?
Here we go. So 3 days ago I got my DPF removed (physically) and today I got the car mapped out at a tuning place. They did a good job with a new map, turning DPF/EGR off via software.
However, since I got the DPF removed I began hearing this kinda whistling noise everytime I rev the car. It stays for like 2/3 seconds +/- and then goes away until I rev again or take my foot off accelerator.
I have not seen any kind of white, grey or blue smoke. No hissing, cluttering, knocking sound. My car has not lost performance either. It is not down on power and drives really well.
It is really strong and puts more power down now that it has been mapped out. I am not sure as to why I hear the whistle now. My only guess after doing some research is that... The whistle is from the turbo spooler? It is more easy to hear now because DPF has been removed and there is no restriction on turbo and its performance?
If the good people can come back to me with some explanation and reasons for my query it would be much appreciated!
Thanks
