Hi all I recently had my audi a4 1.8t 163bhp remapped and on acceleration I can hear a sound like it's leaking boost and it's not accelerating how it should hesitant etc I've had a boost leak check done and it's fine I'm wondering if it's the diverter valve not coping with the added boost...
Had the remap done defo feel the difference don't know the actual gains in numbers until I get it dyno'd...the turbo makes like a little screech noise I guess that's the diverter.Will take it for a propper run tomorrow as I had my 11 month old son with me sat in his batman car seat lol.
