Any other ideas I should be looking at? I don't want to tune.

You're going to lose 130 bhp or more on a stock LT4. You can't recover that unless you make some of the mods discussed here daily. An E85 Flex Fuel kit and a tune are probably the least expensive ways to regain power. You can spin your blower faster too but additional heat will be a problem.
