the new set up just has 1000 miles. and since the dyno i have only drove it about 20miles that is the distance from balanced perf. to my house, stopping and turning the car off everytime that the temp. is about to hit the red mark.

the car turns on, and works just fine, if i keep it under 3k rpm the temperature stays normal, i let the car running in my garage for a good 30 minutes and the temp was normal but when i took it for a test drive and floored the gas the car jerks and shoots out the coolant and the temperature raises and just keeps bouncing up and down.
