Guys,
Wonder if someone can advise, I'm having some issues with overboosting (as fun as it is can't imagine my turbos are going to last long if I leave it) I'm running standard J-Spec turbos with a HKS boost controller, I've just re-installed a standard air box with HKS panel filter.
I've recently has other issues to sort out and whilst it was in workshop I decided to get a full de-cat fitted and fit a 1 Bar RR and I thought we had found the problem.
This is my Controller as not sure what the actual name is:
Exhaust Before:
Now fully de-cat with RR in place
Finally got chance to take it out today for a test run today after other issues being fixed and still my boost gauge is reading about 1.55 bar with controller off so switched it on and the digital reading hit the same (thought my be a gauge issue) I switched the controller to 'low' setting which appears to be set to 0.9 and no change in boost??
Does this lead to a controller issue or is there something else I can try?
