... i should be alright without it for now ...

And you Know this how? If you don't have any feedback telling you you are alright, then you don't know... You're assuming.

You're running 16psi on 57trim with lex/550 and walbro plus 3"ddp - VF is not sufficient.

Why bother asking everyones advice on here and then ignore it?

im not ignoring the advice, But from what I understood was that the lexus afm and the 550cc injectors, would keep the system stock in terms of running, normal fuel calculations and everything appears like nothing has changed to the ecu. But this combo allows the fuel map to keep going past stock so you can flow more air and then fuel cut is still there to put a limit of where the system has reached its limit. That is only what I thought.

You are still not getting the point about consequences. Without any hard data about how well your car is running you are assuming all is well when it's not. Running the Lex/550 does compensate each other and pushes fuel cut up, but fuel cut was there for a reason. You have to remember also that at these levels a CT26/57 will put out more lbs of air at the same psi of a CT26. Tuning devices, data loggers, wide bands are a must in modifying just as an exhaust system or intake system. They are necessary to get you were your going without consequences.

Sorry to sound like an arse... but we don't wanna see another supra sit next year out.

I think that pretty much sums it up
