Not holding boost.....any suggestions
Took the 1.8TQS to Chipped UK for a re-map
Dyno before: 156bhp - :scared2: well pee'd off - it's supposed to be 180
After :189bhp with the acknowledgement that we would be over 210 if the turbo would maintain boost. There was a leak/early DV operation- unknown problem. They also thought there may be a problem showing on the dyno, but might not see it on the road.
I do notice what seems like the turbo slowing, acceleration not quite as it is at 2,500rpm to 4,000 rpm.
I pointed out that the pipe from the intercooler to the throtle valve had been hacked in to to add a dump-valve, and whilst I had removed the DV I left the branch pipe in.
They said it would have an effect - so I replaced it on Friday with a shiny new Audi OE part, a little difference.
Could it be the turbulence that this caused, or could the Diverter Valve that I replaced into the system, (when I got rid of the dump valve) be the problem. I got an OE Audi part. All pipes seem good with no splits or aparent problems with junctions...
Must say the turbo now kicks in hard
