my s1 rb25det has trouble going back to idle

[hungarien drifter]

i have a s14 with a s1 rb25det swap and everything is cool on it except when i rev it up to like 3 grand and when it drops back to idle instead of stopping at like 900 rpm it almost dies and goes to like 200rmp and then goes back to normal idle. would anybody know what is going on with it cuz its really hard to drive when it doing that.????? please help me out???

Boost leak perhaps, your BOV recirced?

[hungarien drifter]

no its not recirculated. and if its not a boost leak what else could it be?

[eh?]

You need to recirculate it.

theres your problem sir.

[hungarien drifter]

is that the only way to fix that?? cuz i really like the sound of bovs

If its not the BOV it may be because you are running a greddy manifold or q45 TB... my car did the same thing and it was not the BOV.

your mafs might also be effed (or your ecu)
