Everytime i run the car hard a few times... my car starts to overheat.... but drops If I start driving normal. I am boosting 10lbs. My autometer a/f gauges says I'm running rich and one or two yellow box in stoich. Am i running lean? I am currently using the VAFC hack. I do not hear any detonation. Anyone of yall guys got any suggestion ? Thanks in advance

 

how does your fluid look?

 

have not check it yet ? I just recently change my headgasket not too long ago. what should i look for ?

**only overheat when I driving hard and slightly goes up when I pass a car on the highway, but drop instantly after I am crusing at mild speeds

Are you sure you don't have air trapped in your cooling system?

I'm not sure about that, but that is a good idea,could that be the reason why my car is behaving like that? because when I put the headback together and installed a new thermostat. Filled the motor with fluid, but never pump the air out..I remember my brother did it for me the first time before I blew the headgasket, but not after. I am going to try that, but is there any other suggestion too ? Thanks

 

that sounds like it's air in the coolin system
coz if u just feel it, and didn't blee it, 100% air then
