Hello, i have just changed my air intake, removed the cone filter that was on and ive put the stock air intake box back on. I first had some problems with the car stalling out when i first changed this over, but after checking vaccum lines i managed to sort this problem out and it idles perfectly and doesnt stall out.

BUT, my problem no is that the car seems to have a power loss when i hit 3k RPM until 4k RPM, then it starts to pull away after 4K RPM. It only seems to do this since ive changed the air intak over, ive cleaned MAF, and reset the program with the 20 brake method

Any help on why im now getting this power loss would be great!

Thank you

Did you put the VAFD back on as well? That is the part in front of the air intake. If someone went cold air with a cone in the engine compartment, then it likely needs hooked back up. I think that is what ^^ is referring to, but I keep staring at the picture and do not see the words...

There will be an electronically controlled valve on the air box, and a vacuum line that runs to it, and away from it up to the valve. Look for steel lines.

I think i know what that valve is, located on the back of the airbox correct? i have an airline going from that to the front of the intake

okay sorry, i just looked up the VFAD, and i have all the lines installed correctly going where they need too
