Too rich mixture at boost

Hey Guys

I have trouble driving my Glanza because it is running to rich at boost. The turboboost is at 0,7bar/10psi, but it some times peaks at 0,8bar...
At full throttle it feels like the engine is holding a bit back?

Mods: 2,5" exhaust, KN-filter, FMIC, another actuator and a turbosmart bleedvalve.

Here's some pictures running the car and two videos..

I think mines runs very rich at boost as well, but I don't understand why, the ECU and fuel pump are standard. I have a Sard FPR and wonder if that is the problem, the funny thing is if I recet the ECU it runs fine for a week or so, then gets rich again.

The car is standard becide the mentioned mods.... I have tried to reset the ecu, run it with and without the hi/lo function with no difference.

It's probably the FPR, you dont need that kind of fuel mods on 0.7 bar.

Set it to 1.0 bar and try again.

I'm running 1 bar as well with stock fueling, only FCD. And mine also runs the rich side on boost low 11's

^ you run 1bar of boost with no fueling mods just a fcd?that sounds abit risky to me...no fpr mods or uprated fuel pump?

Well actually i have a inline walbro 160lph and a greddy emanage blue, but i only use the greddy as a FCD.

Other that that, nope.

Just open air filter, mani, downpipe, exhaust, big FMIC etc.

And i have a AEM wideband to check, it's fine, been running for almost more then a year now.

The car is a EP71 starlet.

Gonna up the boost to 1.2 bar soon and add some fuel with the emanage, and get it professionally tuned on the dyno.

Car goes like a madman.

Well basically that's what i did mate, the greddy emanage isn't doing anything. not adjusting fuel or anything. It's only functioning as a FCD.
