One of the best/cheapest mods I ever did to my 300tdi was taking the signal for the boost actuator from the rear of the inlet manifold, this opens the wastegate once the boost reaches the manifold not just the otherside of the turbo.
Is there any benefit doing this to my TD5?
Im about to tap the inlet manifold to fit a boost gauge so could re-route the pipework while Im there?
Il obviously seal up the hole on the intercooler pipework
Thanks for looking
