I had the same problem. It was related to my power FC and my settings. If you boost over your target you will hit a fuel cut. When you hit the fuel cut, do you have to shift to get out of it? Thats what I had to do. I found by changing the duty cycle settings (lowering them) will stop it. But I also found it depends on the weather.

If you are running a PFC - ZeroBanger has the answer
If you are still running a stock ecu it also fuel cut. (cuts at around12.5psi on the stock ecu)
what are your mods - you must be running a MP or gutted cat to throw flames.

I had the same problem. I know this is elementry, but check your couplings form the IC. Mine were a little loose.

Thats because the supra is a big fat pig and will take forever for it to get moving again.


Hows your 7?

He does have an FD guys...

Anyway, what mods are currently on the car? It sounds like you are hitting fuel cut.
