Losing my shirt on this car. It has almost no power, and literally 0 power above 2500rpm. Won't rev past 3000rpm under load. When revving in neutral, it is sluggish and when it hits 2000rpm it struggles to push through to 3-4000rpm. With MAF unplugged, the engine will not rev above 2000rpm in neutral, and smokes like crazy (getting fuel, obviously).
Have removed all intake and exhaust parts, no restrictions. Turbo works perfectly. Boosts to spec. MAF spikes around 600 at 2200rpm, and drops quickly to 400. Tried known good MAF. 12v, 5v and ground are good on the MAF connector. Compression is 490-500lbs across the board. Tried a used set of injectors, and injection pump. Timing is bang on. Fuel pickup is new, no restrictions to the fuel filter. Air and fuel filters are new, no snow screen. Valve train is intact and looks good.
I'm out of idea's, besides a weird fluky ECU issue or an internal mechanical problem of some sort.
No trouble codes, and boosts to spec.
Hopefully someone has an idea or can spot something i've over looked, before I put an engine in this car!
