CC503 Roadtrip Results (MPG)
Let me start of in saying the car ran great!
M6 3.42
CC503
918s
Promag 1.6 RRs
PP heads (minor, mostly in the exhaust ports)
3 angled
11:1
LTs
magnaflow catback
ORY
MadZ28 tune
MSD cap and rotor
Magnacore wires
K&N CAI
got 347.7miles before fill up and it averaged out to just barely over 23mpgs
the tank before that I got 16.5 mpg in the city, I have a heavy foot in the city, but for running the air and driving in the rain the whole 200 miles back @ 65mph
I drove at about 75mph on the way there with a 115mph run to catch up with my buddies (I had to stop and put the T-tops on, it was starting to rain)
So 23mpg...I guess I will take it.

Ya, pretty much every bolt on except a ewp. Light work done to the heads and intake, pretty much just gasket matching. Koni's on all 4 corners, sub frames, lca's, tune, 3.73's, eaton diff, alum ds, new hi flo cat(magnaflow). The car is not lowered. Which would help.
The biggest thing which helps so much is the extra air in the tires and just getting done waxing,glaze, compound, claying the car.
Im putting on springs, a panhard rod arm, re location brackets and after I adjust the camber and caster to more road race settings I think I can break 30mpg's. I also need an alignment which will help me with my goal.
There was a thread about doing it a few weeks back. I think the best the guy did was 32mpg. Oh and I re balanced the tires about a month ago. Plus i have re built the top half of the motor due to headgaskets and also replaced everything. O2's,plugs, wires, fuel filter, rebuilt heads, new opti and waterpump, etc.
The thing is you have to leave the car on cruise control. No touching the gas, I set it on 66 and left it.
