Blow off valves?

No no, Turbo stall only occurs when you have:
1) No BOV fitted (On FD anyway!)
2) Nakerd BOV
3) Poorley adjusted BOV

Aftermarket ones shouldn\'t produce any turbo stall!!

personally for me BOVs are just noise makers it may lead to a longer turbo life but I remain unconvinced, in terms of performance you are losing a little as a BOV vents all pressurised air out of the intercooler and pipes and the turbo has to work a little harder to pressurize the system again, so you actually increase lag a little between shifts

Here is a big discussion on Ausrotary about BOVs some fact some fiction
