ca18det cut off issue

[shadowdragonx]

I just finished my ca18det into a usdm 240sx swap

the thing idle's good, but when i was taking for a test run, every time it hit's 5psi of boost, it feels like you've hit the rev limiter or something and it starts choking until you let go of the gas.

i've tried to pull codes, and the only code i get is 55
i've tried adjusting tps, and timing
i've tried to clean the maf sensor

anyone got any idea's on whats wrong?

what'is the max rev that you had??

if it's 2krpm,it's the maf>dead.

another question>what's the turbo??

the stock one??(t25) or a bigger one??

[shadowdragonx]

max rev's i can get is between 3 - 4krpm
it all depends how hard i am on the pedal, but no matter what when i hit 5pounds of boost it goes crazy

yes it is the stock t25 turbo on the vehicle

boost leak check your piping ten times
then check for vacuum leaks
