(combo in sig)
So after winter storage I had some issues with an injector not firing. Sent out the ECU to have driver replaced and the car starts up and idles and drives perfect. All scan master items in check. MAF readings are normal. Only CEL error is a code 23. Which I always have. I'm using a turbo tweak chip and don't need the intake temp sensor.
When I go WOT, boost will build fast to 24 psi or so and then the car acts just like a coupler blew off. It starts to loose power quickly and bleeds off boost, then it abruptly falls flat on its face coughing and sputtering. At this time the AFR gauge pegs dead rich. I'm getting no knock readings.timing is at 18* AFR's 11.6:1. Compression test is good all around. I pressurized the inlet of the turbo and checked for leaks on the entire car. There is a slight crack in the intake manifold I've had since last season. I need to fix this, but the car ran fine with this small crack all last season. I leak checked the system to 40psi and had no other major leaks.No couplings blew off etc. I don't run a BOV. I just don't know where I could be losing pressure at?
I replaced the MAF with a spare unit I had with no change. Turbo is new and tight. No smoke etc.
Car runs great other wise. I'm stumped... again!
