Question Vishnu Tunning Question

Currently , I'm running a Stage 0 vishnu setup. I bought all the parts that make up to a stage 2 vishnu setup. I just sent the chip(unichip) to get re-programmed by vishnu for the stage 2 setup. I guess I planned on putting the Turbo, Fuel Injectors, and the Fuel Pump in at the same time...basically when I go the chip back from Vishnu. My question is this:

Once I get the chip installed and all mentioned above (turbo, Fuel injectors, and pump), does my car then need to be tuned accordingly or does the chip handle the fuel management from there?

I guess I'm concerned about the fuel, and whether or not the chip will handle the new sti injectors, and fuel pump....if I will need to get this professionally tuned...etc.

Please help...any suggestions?

you do have a turbo back and uppipe right?

ok,just making sure...

if you have all the *same* parts as the vishnu stage 2, you should be okay. the unichip will come back tuned for the stage 2, so it will assume you have the injectors, turbo ,etc in already.

don't put the unichip in w/o the other parts in first.

don't put the turbo and all the other stuff in w/o the unichip



*same = about the same parts, if you have a perrin uppipe, it doesn't matter. if you got a pe 1820 then you might have a problem. *
