Unhappy Gas Mileage with CAM ?

my MPG seems to have taken a **** now... I'm getting 130-150 miles per fill [as opposed to 250] city driving.. and I'm literally just feathering the pedal !!

Does the MPG take a huge hit with a cam ?

Mine took a **** after the cam swap too. I was hoping that after I had it tuned, it would save a little more, but nope.

Mine is similar to stock and hasnt been tuned. I keep the rpms below 1500 though. I think that helps. I also run 6th gear at 40mph and it has the stock 3.42 gears. That probably helps.

I get about 17-19mpg or about 220-240 mpt. I have the TSP 225/114 with a M6 and 4.10's. I was getting about 20-21 before the cam. This is mostly city driving though. On the highway I get about 180-190 miles to a half a tank.

I am at 155 miles on this tank and I am under a 1/4 so I figure I will hit 170-180miles on this tank. Thats with about 6 passes on the tank and a little bit of hot rodding/burn outs etc. If I was to drive it normal, I would say I could get 190-200miles per tank. Not to good. bout 13mpgs. Its that fat tune thats killin it.
