Hi! I´m running with phase 3 and I´ve got strange problem....When I am running with full throttle my AFR gauge shows only one led at lean side.It does´t matter if the switch is on position 1 or 5.Everyrything is great before turbo is giving any pressure, mixture is on 4 leds green in normal running, but when I hit even only 0.3 bar pressure mixture goes lean and car is holding back. When I hit the full throttle AFR gauge is 1 led on rich side 2-5 seconds before turbo is giving the pressure.
I´ve got new 909 fuel pump,relay and thicker wires to the pump.Pump is getting 13.9 volt when driving
My fuel pressure gauge shows over 5 bars when full throttle and 1 bar boost and about 4 bars when idle.
New coolant temp sensor (GM part)
New lambda sensor (GM part)
Clean K&N air filter
Silicone hose between turbo and air filter box
Air mass meter has been checked with multimeter.Measuring terminals between 2 and 3, I´ve get 4.3 volt when full throttle.Goes smoothly from 2.2 volt when idle to 4.3 volt when full throttle.
I really dont know what to do so please help me....
