Hey guys as some of you know I recirculated (well minitoyota did) this winter. Recently I've been having some spiking where I would hit fuel cut in high boost. My tuner and I have gone back and forth trying some adjustments over email and after a couple tries I decided to drop the high boost down to 12 to just avoid the situation of boosting too high. Anyhow the thought is it my wastegate recirc may be too restrictive. Anyone else having this issue? I'm tempted to leave my boost at 12 since that seems plenty fast, but of course more is can be nice too .

 

I've had the issue in the past. Decided to ditch the recirc and step up to an open Precision 46mm.

In the meantime, you could try lowering the boost in the RPM/Gears where it starts to creep and see if that helps

 

justin you got your caR back? lets meet up i finally put mine back together!

btw i just re-did my WG to go through my hood, no more spiking issues. is the diameter of the WG dumptube larger than the ID of the WG outlet flange? how many bends in the dumptube? does the dumptube go back into the exhaust at a steep angle, or a low angle? all those will affect the resistance

Open wastegate & zero creep
