nope, got a tune after the first cam swap. then swapped it to another cam and haven't been back to retune. so not sure if thats my problem.

I have about the same mods listed above, except a power flo exhaust, best I've seen was 350+ per tank on a 1100 mile trip, that equals out to 27 MPG.
I've got an M6 with 3.73's
This trip pushed it over to 51,000 miles.
Has about 18,000 on the NGK plugs and I changed the fuel filter a few times.
Stock tune.
With the mods in the signature, except for my new additions (the FAST90, nw90, 30 lbs injectors, and 85mm tb) with an M6 I was getting 320+ miles per tank on the highway. NOt sure what I am getting now.
