I have a f-max kit in my 2000 gsr. do you have the f max piggy back hooked up? Well if you do check the instalation on the computer. did you even get the car running with the turbo kit installed? when I got mine running it ran like crap the 2 injecters on the intake pipe is bullshit it ran super rich and felt like my motor was going to blow up. Also had problems starting the motor was always flooded. so I just went the old fashion was bought 4 440 rc injecters fuel pump fmu and now I use a VAFC as my piggy back. these might not be your problem but I hope it helps.
