Dyno demon rr

Dyno Demon this morning to check car before planned trip,
& we did nt make much noise on standard everything

Doesnt look like a boost leak, it looks like the boost controller isnt doing a very god job. Are you still on the original EBV? If so you could get better results with a PRV.

yes.....

opperator did point out there was a hissing noise arround throttle body which i couldnt hear at the time but can now...is this normal on tickover ?

thanks again
