    I am also in FL and I would say that is average for the summer here. The water temperature is always over 80 degrees in the summer. I gain 200 rpm when it get water get into the 60's.

    In stock you may see 7650rpm .
    Keep an on belt tension and the blow off valve at the back of the intercooler leaks sometimes,,,you can block them off.
    Lost of Boost is a lost in Revs.
    Wait to yo get up to 8400 rpm then you here the engine sing.
