I got round to fitting my new forge DV (off MABR's group buy) a few days ago and last night I had a late run over to Tamworth and back. This gave me the opportunity to try the acceleration and take the revs up to near the red line.
Now with the standard DV I always got a very metallic (Bee in a tin can) noise just
before I came off the throttle to change up a gear.
Now the noise has gone and I seem to have smooth quiet boost up to the change (nice).
It was a nice cool evening and so I seemed to have plenty of power and it was running so smooth.
I tested the old DV for leaks after I took it of and it was fine.
So what was going on before ?
Was I losing boast through the valve before time ?
Or was the standard DV supposed to release boast at lower pressure for safety ?
What ever it is I'm more than happy with the results
P.S Does this mean I,m now on the rocky road of engine modding
