max boost you can have on s4 ecu
 

so whats the max boost you can get out of the stock ecu. i bought a garret turbo for really cheap and i need to know what the max i can get out of it with everything else stock.lol

the max you can get out of it..is just before it goes BOOOM..
Put a different turbo on that engine without doing any fuel mods(stock Ecu)?.disaster.

i dont want it to go boom so thats why i asked. i know the ecu and fuel system can only handle so much. i want to know whats the max i can go without going boom. stock boost is around 6 from what i read

stock turbo maxes about 12 psi,but you are leaning towards putting on a different turbo with different specifications,and for that it is anyone's guess.
If you use a boost controller you may be able to run safely,but it all depends on what the turbo makes the engine want fuel wise,and for that you need to compensate.
So,just slappin on a turbo?..nope..need more parts..
