Turbo issues!

[al67]

Hi all,

I hope someone here can give me some info or help in some way...

After having my 1.9tdi Passat B6 re-mapped a couple of months ago, the turbo has started to whistle when excelerating. It was so underpowered when overtaking that I had to do something with it, and it's now running 155bhp and 365nm torque and pulls lovely. The turbo has been off and there is no play or anything that looks wrong, so what is going on? Do I need a bigger turbo to cope with the extra power, help please? If so, which turbo and manifold would do the job?


Thanks for reading my blather.


Al.
