Not much power gain but the sound gain is nice....
As for the resistors....i have a bunch of them as well as other electronics...as electronics is my line of work so to speak
Now for more fuel i also mounted larger fuel injector and custom valves + Valve timing contoler....and remapet the ECU
So now im looking a way to get some more power trough electronics.Thinking of DASTEK unichip Piggyback unit (10-15HP -dyno tested) but its expensive... 700€ unit+200€ for map....
Does anyone has some other ideas on what to do to gain some more power?
(dont want to hear about tubo  )

The mod you have made to your intake may have improved the flow of air by a few percent (<5%), certainly NOT enough to warrant larger injectors. There is no way of controlling the valve actuation (hydraulic or direct off cams, with no electrical involvement).
The only electrical "modification" that DOES work is to have the ignition map of the ECU altered and to run the vehicle on higher grade fuel. This is what your Dastek unit sort of does by fiddling the outputs of the injector pulses. Depending on exactly what model Kia you have you may find a similar replacement/altered ECU chip from
www.powerchipgroup.com. I have had one of these fitted to my '02 Sportage and it DID make a difference, mainly due to the OE ignition map calibration set for 87 octane, whereas in Australia our lowest octane rating is 91 (same as the calibration chip I bought), which allows the ignition to be more advanced.
Another couple of ECU options you may want to look at, given your background, is the
MegaSquirt I Programmable EFI System PCB3.0 - UnAssembled Kit or
Wolf Engine Management - Engine Management .
Most ECU/injector setups will handle a few pounds of boost without needing new high flow injectors (up to about 5 psi)
