    I have an 86 oldsmobile cutlass supreme with the olds 307 v-8. My complaint is that it is very lacking on the power side and very bad on gas, I only get 12 MPG when driving a mix of highway/city. I'm in school at Nashville Auto Diesel College and I set the timing on it in class, the factory spec says 20 degrees BTDC. That sounded a lot for me and the teacher but I set it at that, it was at 15, I didn't notice any more performance. I guess my question is what would be causing me to get such bad gas mileage and what can I do to get some more power out of tuning it up. It has the E4ME Quadrajunk also. Anyone who had a car like this I would like some help. Thanks
