As above when i de throttle I get a loud whistle and when back on the throttle it goes ... Think it's a vacuum leak but can't find it anywhere it's down the right side of the engine as you look at the car... Any ideas would be good cheers

 

What mods does the car have?have you also moved anything about before hand

 

Any difference in power?

 

Front mount
Walbro pump
Td05 20g
Meth
Full decAt turbo back system
Lightened flywheel

Yea just running it in and hasn't done it since engine went in a week ago
Cheers

Confused

So you are running in an new engine?

What hasn't done it since the engine went in?

Your running it in on Meth?

What car is it?

 

Have you got one of them bell mouth down pipes or is it the divorced one?

 

Bell mouth downpipe ... It hasn't done the whistle noise it's been perfect until yesterday ... Meth isn't in tank as of yet as I'm not doing that until jgm fits and maps alcatek
