My car also has upper grill blocks, stealth. For city driving it is all about accelerating and momentum. Although you have approx a 400lb weight advantage on me (lighter) and a smaller engine, I think you will get more pay back in with driving mods. Not saying not to do the mods, do them. But your pay back in the city will be minimal.
With my car it needs to get to 47 MPH and hold it for best mileage. The 80% load doesn't work for me. There is not enough distance between many lights to recoup the MPG loss used during acceleration and the car is often carrying too much momentum at the next light which always seems to turn red.
The two biggest city fuel savers for me are:
1. No AC (when I'm alone)
2. Engine off at lights
The 3.8 is very thirsty at an idle .39 to .47 GPH after reaching operating temperature, depending on how hot the day. Don't like to key off though, in dash ignition switch was $500. Another annoyance the DLRs (daytime running lights) come on with each restart.
