Removing Return Pipe In 32 Gtr

[davedemko]

i want to change my cooler piping and bov and i have tried taking the return pipe off and blocking it but it runs like shit

a mates told me that i need to get it tuned, if so is there anyone in western sydney that tunes MINES?\

and is there anything else involved??

RB26's run AFM's standard so with the return pipe blocked off u'll get rough idle. You could run a Djetro PFC , then u wouldnt need to run the AFM's.

though howcome that happens with the AFM, the return pipe isnt in direct contact is it?

You cant block them, they leak @ idle/low throttle deliberately to avoid compressor surge.

Changing the GTR piping can cause a fair amount of problems, your best not to touch it at all. Sounds like you have a fairly stock car given you dont really have a ECU - so no need to change piping

Also you have a MINES ECU - basically a throw away item as there is no point trying to get one tuned IMO.

Just replace with PFC or other ECU.
