My car have the same problem but i have a 2001 Accord turbocharged. Well, i just done installed the turbo and tried a test drive. First i started out going about 10-20mph, then 30-40, and so on and it performs fine to me. When i decided to step heavier on the Gas peddle to see how much different in speed when turbocharged and not turbo, but then there's like a sound as it's losing power and the car wants to quit (but the engine still running). I have installed 450cc injectors along with the FMU. Do i need anything else or an Apexi or something. Does it mean when i replaced the stock injectors with the 450cc injectors plus the FMu, will the Fuel automatically pump more fuel to my engine or the Engine still reads stock fuel until i tune it up with the Apexi???? Please advise if anyone knows what's the problem is? The car only performs like that when i have the Turbo connected to the intake, but when i disconnect the pipe (stop air going to the intake) then the car is doing fine.
