MPGs with 37s
I just want to preface this with I didn't buy a 7.3 and put 37s and expect good mpgs. so i have 01 CCSB 7.3 with an 8" lift and 37x13.5R22. I was getting 11.87 mpgs around town and highway like 12.45 and that was with stock injectors, turbo leak, up pipe leaks and stupid hot tune with an edge tuner.
I just put in the KC 300x 63/73 turbo, 180/30 injectors, boost fooler, banjo bolts, fuel cross over, a few other little supporting things and have the tunes from full force and run the "daily tune". with all that being said I get the same exact MPGs.... now I have way more power as my truck runs way better but i'd thought is at least get 15/16 mpgs. does this sound normal to y'all or do think something isn't right that's causing these lower mpgs.
