Hi, I have a 92 MR2 3SGTE Gen2 for some reason the car cannot go past 4.5K rpm it bogs when its around that RPM i've checked fuel cut or ignition cut i do not spot anything. Car has 264 HKS intake cam and Gen3 intake cam flipped 180 degree for exhaust cam. I have a map and log under my attachment, let me know if anyone spot any problem. Thank you in advanced!
I'm really not familiar with these cars and engine, but have you check fuel pressure to make sure you have sufficient flow from the fuel pump? If you look at the picture I attached, it seems to have leaned out with no apparent reason at this place (VE still raising, Rpm climbing, MAP and TPS are stable...)
