Default HELP car overheating after VF39 install

I finished my VF39 install earlier and just flashed my car with the accessport. I started it up and everything seems ok. I filled up the resevoir and the radiator with coolant but it slowly kept getting hotter. The coolant was a mix of 50% subaru coolant and 50% water. I just turned it off and I'm going to wait for it to cool down and see if it needs more coolant. What went wrong? I'm not losing any coolant under the car btw.

Did you bleed the system (ie. lines going to the turbo)? I believe you need to do so to eliminate air pockets in the lines. Could be wrong.

100% chance of air bubble. This is a common thing.

I think you're right. What I also forgot until a little while after I posted this was to squeeze the radiator tube to pump the coolant because after I did that and then let it sit, it needed a lot more. It seems to be ok now after about an hour of driving. I'll definitely check it out tomorrow as well.

It will go away, and when it does, it won't come back.

I just did a vf43 install and I do not have heat issues, however I did spend about 20 min clearing air bubbles (squeezing the tubes) also I clamped the hoses to limit air bubbles during the install.

Make sure you keep your water levels toped and over fill the at the radiator cap (spill when closing) and it will go away given there is not a leak somewhere.

I have been running for 5 weeks now, no Problems what so ever. How do you like the power?

burp the raidiotor hose coming off the radiator and turning towards the air box after opening the coolant cap at the bottom left of your TMIC. do this until bubbles stop coming up and put a towel around this area b/c it will splatter a little.

The power is great but I'm pretty sure there is boost leaking because I think it should be more powerful. I mean, I can feel the difference but it seems sometimes it pulls harder then other times, for the reason stated at the bottom of here:

Are you still having the overheating issues.
Are there any other problems you are experiencing?

Nope, It's not overheating anymore as I stated above. The only other problem I'm having is at this thread:
