Here are a pack of c13 iva off files. 470hp 1650tq these are unplugged files. I keep the wiring plugged in tho just to keep it from getting caught on the rockers. Back off your ivas. You can unplug the external sensors. Ive ran both twin turbos or a c12 single turbo and they do great. I will send a link thru messaging. Paste it to google and it will auto download. Once downloaded, right click it and unzip it with 7zip or winzip. Thanks!
