[QUOTE="01cobravortech, post: 4469618, member: 14885"] Bob, the Voretch is off and sitting around. I almost want to say that the old motor had slightly better mileage with the Vortech on and 4.10s. I don't believe that the current stock motor has a 'health isues.' No real unusual oil consumption and all the basic bolt ons that help it breath better. I do remember that between the first 25,000 miles the motor was getting about 320 miels per tank and that was with 4.10s. BUT...I also had a C&L meter on the car then, along with the previous custom tune. Stupid me went to get the car dynoed at around 25k and thats when I found the A/F ranging from 13.0 - 17.0 throughout the power band. Needless to say, thats when JLT entered my life. But its interesting to note that while running lean I was seeing my best fuel economy. Of course that wasn't healthy, but maybe I have a fuel economy dud compared to the rest of you guys. I'm going to try these WeaponX COPs. Maybe I have something as subtle as that affecting my fuel economy. Its worth a shot because I've troubleshooted the heck of this fuel economy issue with no luck.
