Is not change nothing, this is my problem

Think of it this way, you can drink 1 500ml glass of water a minute
so if you increase the size of the glass to 1000ml, you can still only drink 500ml...

well thats what the computer is doing, if you want to change that, you have to trick the computer

Uhmmmm ok and if install a malpassi 1:1 fuel regulator ?

Adding larger injectors will only help increase power if you can increase the quantity of air entering the engine.

Adding more fuel without additional air going through the engine may actually decrease power at times.

Ways to add more air:

1 ) Decrease resistance with Cold air intake and low resistance filter
2 ) Port/Polish cylinder head
3 ) Change Camshafts ( you can use Opel Cam shafts )
4 ) Install a performance exhaust header ( again you can use Opel parts )
5 ) Install larger exhaust with less restriction

The largest gains would be from a performance cam shaft.

Which engine do you have in your lanos?

[Daniele84]

The main problem of lanos is the lack amount of fuel injected, there is more air than fuel, i have a 1.6, now I bought the fuel pressure regulator. i try!

[benzino]

how do you know that?

is it running lean?

[jorge]

You need to use a air/fuel ratio controller

[Daniele84]

In fact, I just bought a pressure regulator.

[benzino]

that's not what a air/fuel controller is

more along the lines of an Apexi SAFC...

so how do you know that you are getting to much air/running lean?

[Daniele84]

I will do some test driving, of course, the adjustment will be made ​​by eye and checking the spark
