I'm Running a set of cbr 954 itb's on stock ecu. The Air fuel mixture seems right enough. It runs a bit run at low RPM and a bit lean on high but all on save figures. When i rev the car on natural there is no problem at all. When I start running on every gear i press the throttle a bit too hard and the engine starts choking and there is no power at all. Only i get acceleration by pressing throttle really slowly.Is it the transmission or i need longer velocity stacks i dunno any suggestions?

get a wideband O2 sensor to see how lean you are running. because you are driving, you are putting a stronger load on the engine. I think it is leaning out. you might need a larger injector

i have a set of 7mge injectors. But when i put em on the car is WAY too rich at idle. High Rpm seems right.ill see what i can do
