To begin, here's the dyno.

Here are the mods.

RS*R GT-2 80mm exhaust
Koyo 2row aluminum radiator
T3 Flanged Manifold
ACT 6-puck clutch kit
SARD Blow off valve
R/C Engineering 550cc Injectors
Walbro fuel pump
24" x 12" x 3 FMIC
TiaL .38mm wastegate (.5 bar spring)
Garrett T3/T04E .57trim .63 a/r /w DP Flange
Fuel pump hardwire kit
EGR Blockoff Plate
z32 MAF
Enthalpy Tuned ECU
NGK BKR7E11 gapped to .030"

I bought the Enthalpy ECU used but I am told it was tuned for 550cc/z32 MAF.

We checked the timing and this is right at 20. I did at a pull at 15 and the same thing happened, though a bit less pronounced. Mechanically, everything seems to be in good shape. I'm really not sure what's happening here.

Thanks in advance.

did you forgot to list injectors or are you still using stock 270cc ?

wtf is going on @4k? looks like your engine dies then picks up a couple rpm later... doesn't look too much fuel related because the afr dosn't seem to have much effect on it
