How about some things in the power department!! Like the latest trend of turboing, ease of installation and power potential and mileage. Right now turbos are the only power adder that offers unlimited power and no decrease in mileage(besides nitrous). I know guy with a twin turbo Ls1 car that could offer all the insight in the world!

Also, maybe more on fuel injection tuning to lessen the scare people have of these two things.
How about some articles on turbo LS1's (Cause everyone wants or has one) and how cheaply they can be built with entire parts breakdowns! Most people think it is ungodly expensive, I tell people otherwise.
