My buddy that lives right across the street has a 97 vette. napa blue in color. His rear bumper fell off the first day he bought it. We put it back on and its all wobbly and you can push it in easily. I drove it out to the strip and when I was changing the radio station, the plastic surrounding the stock radio cracked. Kinda flimsy..and if you've ever seen one that's wrecked, you know what I mean

Granted, I will agree that a bumper falling off is pretty poor for the first day that you get the car, but the C5 structure is very good.

How fast were you going? i get 27.7 in my firehawk! i can see dropping a 2 series rear in the car...something with the ratio of a V6 2.73? you would be close to 1500 @ 84mph. might get 40mph there. But certainly not with power adders, and your car is now as slow if not slower than a new v6 camaro

Running low boost won't change the fact that turbos are still a restriction in the exhaust system and add significant weight (head units, intercooler(s), piping, etc.), both of which will hurt MPG even on low boost.
Nitrous is literally just along for the ride when not in use. And if you pull the bottle out when not planning to race, the only added weight left is solenoids, switches, wiring and lines - which is nothing compared to the weight of an intercooled TT setup.
All it takes is a 100 shot to reach your 450hp goal on an LS1. Actually, you'll surpass that, because some of the other items that improve MPG (like better flowing exhaust and a leaner tune under cruising conditions) will also boost power.

only on the highway with flat roads it can happen. my trans am in my sig with the mods gets 30mpg on highway cruise but the city it takes a dump almost less than half of what it gets on the highway. i think with a 4.8 and a light car and good highway gears this can happen with all the proper tuning.

A friend of mine runs an M6, stock gear, lightweight clutch, lightened driveshaft, Fast 90/90 setup, LT headers and matching heads/cam and easily gets 34mpg without weight reduction
That is a big no! Your friend is a straight up liar.
Unless he disconnects 6 injectors and then goes out for a drive and says he gets 34mpg in a full weight f body.

Yeah I somehow doubt that. Not only do you say he 'easily' gets 34mpg, but the guy has NO weight reduction, has aftermarket heads and a cam and has the stock gearset.
