    ls2 problem

    hello guys i have a corvette c6 engine in my chevy truck

    it starts right up and keeps running fine but
    there is no power at all looks like limp mode when i push the peddal to the floor the trottlebody opens 40%
    no codes and 6k on the engine, new injectors and 58/60 psi fuel pressure and new spark-plugs and wires
    there is also no vacuum leak the transmission is a brand new rebuild 700r4 and ecm is set to manual
    the exhaust has no cats but has bank 1 and bank 2 ho2s sensors only the first ones and its running in a closed loop 24x crank and all sensors are new
    any suggestions?
    thanks
    john
