Hey has anyone ever tested AFR's on a 60-1 turbo, Lexus AFM, and 550's with stock pump at different boost levels?

No Tuning, or SAFCs etc?

Just to see what the car did on its own with a setup like this?

Im just curious to see what the stock pump handled, and how well the toyota ECU handled the mods...

I do know that you need a fuel pump. Any turbo upgrade MUST have an upgraded fuel pump.

I've personally seen this on my car with a ts04, and my friend's car with a 57 trim ct-26. With the 57 trim, anything over 5500 rmps and fuel pressure drops off quick.
