i had my turbo kit one day as some of you guys know, i took off right after,...$#@$# (doont ask why)

now i have everything back, all stock parts except my VAFC, but now i have a problem, my rpm is not smooth at 7k rpm, i stuck there for few sec and my enigne sound like it's going to blow, i didnt set anything on the VAFC. is it coz the default setting on VAFC cost this or OBD2 dont work with VAFC ?
my car is so slow now, what should i do. should i just take out the vafc or have it tune ?
thanks

Have it tuned on a dyno with a wideband. Tuning blind with a VAFC is a good way to make piston soup.

In the meantime I would bump your fuel pressure by a few psi just to be safe.

but i dont have the turbo kit no more tho, evrything is back to stock, do i still need to adjust fuel ? if so does this mean that VAFC's default setting is different than stock ?
or should i just take it out, if i do would everything setting back to stock ?

If you're going to stay stock, just take it out.

Uh your statements are a little hard to read to say the least. First off check the basic stuff. See if your car is throwing a code, check the spark plugs, things like that. If you don't find anything try unhooking the VAFC and rewiring the ECU back to see if the car runs correctly. You did remember to reset the VAFC after you went back to stock? If you re-initialize the the VAFC and you are basically stock the car should run find unless you have a bad wiring connection.

If you initialize the set up, i believe it will go to the original vafc setup. This can mean its not set up correctly, i forgot the initialized settings, but im almost positive that you have to change the sensors or the # cylinder car you have. Go though the basic setup procedures in the manual to set it back to stock. But if you are really going back to stock, i would just take it out.

i did reinitialize and only set sensor in 06 out 06 and cylinder to 4, and it's still doing it ! btw when my vtec kicks in my VAFC didnt say it ! it says still off. and my rpm on vafc is not moving only throttle is moving whenever i rev.
does this sound like wrong wiring ?
