Hey guys so I've actually been able to get driving around in my fox after all the work I've been doing on it. But I put a full tank in at the pump it read 12.6 gallons went in. I am almost out and have reached about 135 miles. That would be around 11 mpg. Now I'm going off of the gauge to judge empty. Maybe the gauge or odometer is wrong? The car has : Fresh 302 GT40 upper and lower intake Cold air intake 70 mm maf from thunderbird BBK 70 mm throttle body. 3.73 gears 04 bullitt size wheels Full exhaust Direct bolted fan And an aluminum radiator It has all emissions removed The car doesn't get very hot due to the direct fan which I think could be the culprit ? It is around the "A" on the "NORMAL" gauge which isnt in the middle. Im thinking it may be the fan or I need to tune for the Maf. No codes besides emissions codes. Maybe it's a fuel issue ? What should I look for ? The car is a 1992 hatch by the way. Thanks guys !
