I have a 2003 Trailblazer LS. I took it out to see what it can do. With 275 h.p. and 275lb.ft. of torque I thought in 2wd and it being rwd in this mode it would break the rear tires loose from a standing stop and flooring it. Can anybody tell me if it should. I just got this vehicle and had a new throttle body put on it. If it is not running right, I have a powertrain warranty. Thank you
