Fuel Economy

bsudkamp · #1 (**permalink**) 09-08-2009, 08:43 AM

Oh know another fuel economy question but.... I just had a 6" Pro Comp Lift kit put on along with 37" Pro Comp Extreme AT's. At the same time I had a Pro Flow 4" dpf delete pipe with an SCT tuner set to performance tune. My fuel economy has dropped a bit. Is this normal?

Was the tuner installed previously or was it installed the same time as the lift and tires?

I had the tuner installed at the same time all the other work was done.

The lift and tires are going to hurt your fuel mileage, but I wouldn't think that adding a DPF delete and tuner would hurt it if they were done at the same time. Your mileage should have actually increased

My thoughts also. Is there a burn in period for the tuner with the transmission or engine?

Just drive it awhile, maybe you will start seeing some change
