hi guys

the ZPI guys say "All fuel and timing tuning already complete... " about thier stage zero kit


does this mean that the stock ECU can handle 6PSI?
or does it mean that they give u a pre-tuned ECU???

cause i'm running 5 PSI on my custom kit and i was woundering if i really need an emanage.

 

stock ecu can handle 6psi if the maf is in the right spot on the pipe and such. You will prolly run very rich and emanage could be used to lean it out alittle and gain some more power

 

a good custom tune is the most important part of a turbo setup.

 

i agree 110%

Two posts asking the same thing. Yes you need a piggy back with any turbo system, at minimum. It will help to add power and make the engine more reliable. Please refer to other thread for more comments.
