APR Stage 1 boost drop???

[ongti]

Nope, i dun hav a vagcom but i hav a boost gauge installed and it reads data via the OBD2.. the boost drop should be related to stage 1 coz i tried the stock map and everything runs normal..... and after reading above it does feel like the little turbo is not catching up on producing power...

Could be a boost leaking with the tune selected then. Maybe a loose hose clamp that's allowing boost out under load but is ok at other times. Lower boost on the standard tune doesn't cause the problem.

I had this in the UK on a Leon Cupra, it would go into limp mode if you booted it a bit much when cold. Once warmed up it was good as gold all day long.

Eventually, I found a clamp that had stripped but looked ok. New clamp and all was sorted out. I figured that the hose expanded as it warmed up and made a better seal.
