Boost Problem (Video)

[DarkJackal]

Hey guys,

right, i fitted an aftermarket FPR, and ever since then it shot well over 1 bar of boost and hit fuel cut. After winding the HKS actuator arm to almost full length, it still overboosted. Only difference being it revved up the range a bit slower and took a while longer to go over 1 bar, but it would get there.

Fitted the stock FPR back on, still over 1 bar but slower boosting.

Fitted the stock actuator back on which I had spare, and it still overboosts :/ It worked perfect before so I've no idea wtf is going on. It's a lot slower to boost now but it will go over 1 bar if I let it, but it takes forever getting there compared to the initial problem.

A video of how its set up at the moment :/ Sorry its on an angle, done it on my phone...

Also, I ran it without the actuator and it didnt boost, just thought it was worth mentioning although it might be obvious lol

I know its WAYYY to late but I wanted to know if you had done and filter-to-turbo modifications on the meantime of the fpr change as well cause its a factor as well. the oem intake is super tight and therefore restrictive so in an upgrade you gain tons of intake flow-rate. Very common to overboost on stock setups

Yeah I know but having similar issues with my car so Im interested whats the situation with others as well. Im honestly more curious for the solution,than to actually solve my problem since Im currently not driving my car at all.

many actuators are ajdustable. swapping between them during this may leave it, wrongly adjusted, especially if preowned.
