Hey guys! I got my car running but am encountering some problems. First I filled my coolant and bled the system with the heater on. My problem is when I left the cap off of the thermostat housing the water would fill up to the top. Then I would put the cap back on and go for a drive. Shortly after there would be smoke coming from the radiator. When I take off the cap there would be no visible coolant. What am I doing wrong here?

Next my car idle surges bad from 1000 RPM's to 1500 RPM's. Then when I drive it shutters around 2000-3000 RPM's I have a cruise log on the highway and streets that I will attach. I will also attach my settings that I am using in link. Please let me know if I have something thats making this happen. I also have 3 DTC's. What could make these DTC's show. I never had any CEL's before the turbo upgrade and before I used DSMLink my car ran perfectly fine. It was completely stock but now has a TD05H-20G, VRSF FMIC kit, 3 inch exhaust, LC-1, Stock BOV, Stock 1G MAF
Any help is appreciated!! Thanks guys!

Good deal, you can either replace the front O2 and see if that fixes that problem or just keep running the narrow band sim. All things being equal I'd just keep simulation till the WBO2 died.

That's exactly what I plan on doing! I'm pretty upset that I got another bung welded into my DP. I had to order a cap.
