Alright guys I am pulling my hair out over this damn car and am not sure where to go next. Please help me lol. I’m running a 6262 .82A/r turbo on a RSI manifold with a 46mm Precision wastegate and no matter what I do I can not control the boost over 5,000 rpm. It will stay somewhat near spring pressure (tried 4.5 and 7.5) until around 5,000 then spike to wherever I set the fuel cut, in this case 14.5psi.
I confirmed the wastegate is opening as it should and had a feeling the manifold design was the issue, so I removed the wastegate entirely this morning and found I can hold 0psi until high rpm then it still spools up to 7-8psi! How do I fix this? Will recirculating the wastegate make a difference? I’m just super confused because I know other people have run this combo before and not had this bad of issues. If recirculating the WG doesn’t help I’m not sure what else to try besides a different manifold.
Any help is appreciated.
