I put a turbo kit on my 92 SC300. The car drives fine but won't rev over 3500-3800rpm. I've change the following from stock:

SAFCII installed
Breather hoses left open (the 2 that attatch to the intake pipe)
02 Sensor changed to a screw in type and 2 wires merged to one
Karman Sensor is before the Turbo

I haven't got any check engine lights and the car runs fine and a/f ratio is almost perfect but the car just won't rev over 3800. If anyone has any ideas, please chime in as this is quite discouraging.

What gap are you running on your spark plugs? Is the afc tuned?

if your auto...temp sensor?
just thinking of how autos wont rev high unless engine is "warm"

Have you checked your safc settings?

afc is at "0" across the board. Car is at normal running temp. I don't think its the plugs because it's a straight fuel or spark cut, its not hessitation, like when your spark is being blown out.

What is your car doing? If you blow out the spark you car will hit really hard.. Does it happen if you roll into throttle, without boost? Is your car running rich/ lean? Can you rev past 4k without the car moving? What do your plugs look like?
