Car running rich and retarded timing?

What exactly is your issue, as your post does not make sense.

If you want your car to run properly after mods you will need something basic like an SAFC2 with a tune or step up to a proper ecu.

this was what i could fine http://www.skyline-o...mods-cause.html

when i put my foot down it gears down and then makes this sound like its dumping air or something then after about half a second goes back to normal and boosts..

Is your car auto and is it 'farting' on up shifts? Or are you talking about the cars blow off valve.

Please write an extensive explanation of your issue so we can try to help.

auto gear box on down shift when i floor it it makes i suppose a farting sound, sound like its loosing air and starts to lag.. does it worse on high boost. (say 12psi) after half a sec or so it stops and the boost kicks in and its normal again!

Fuel Cut? Got atmo bov?

[listener13]

fuel cut? and got stock bov

[Jake110]

Ok so the farting noise is the ecu cutting ignition or fuel on gear change. The car is supposed to do this as it cuts the power so you don't blow the gearbox. The is normal, just keep your foot buried. All is good!

[listener13]

but it didnt do it until i put in high flow filter and tinkered with boost..

you have just changed a few things on your car, did you reset the computer???

Pull the positive lead on the battery and leave it for 30 mins.

Start it COLD and let it idle until it reaches normal operating temps.

This sorted out my hunting issues on my shitter RB20 after i changed a shit load of things on it....
