Throttle body's I m still undecided about. If you get a good one I'm sure they can help. But without the help of a properly sized intake I think it would be a waste of money. You could also run into tuning issues if you want to stay stock on the tune. I would recommend a Nick Williams as I have heard that his are very good.
If you have an older C5 a great Corvette mod you could do is upgrade to an LS6 intake. All Vettes did not start coming with them until around 2002. An easy way to tell if you have one is with it off is to look at the underside of it. The underside floor is flat instead of having a curve to it. Its to hard to tell from the P/N's since they differ quite a bit. You could also see with the use of a mirror and a flashlight between the valley cover and the intake for this. Inspect the coolant vent system. The vent system for the heads is different on the LS6 intakes. The back left and right heads have plugs. Where the LS1 system has vent lines running all the way back in an "H" pattern from the front of the engine. So if you do get an LS6 intake you will need 2 plugs and a new front cross over line.
Essential Book for the enthusiast who wants to get the most performance!
This book is essential for the enthusiast who wants to get the most performance out of this engine design but is only familiar with the older Chevy small-blocks. Full-color coverage includes everything you need to know about these engines, including the difficult engine removal and installation, simple engine bolt-ons, electronic controls for the Generation III engine, and detailed engine builds at four different power levels.
Although some manufacturers claim a specific horsepower increase, superchargers actually add horsepower as a percentage gain (percentage of an atmosphere). Assuming an engine with a compression ratio of around 9:1 running pump gas,if a supercharger gives your engine 14.7 psi of boost (another atmosphere) that will essentially double the output of your engine, everything else being equal. After adjusting for thermal and mechanical energy transfer, if an efficient centrifugal supercharger is generating 7.5 psi (approx. 1/2 an atmosphere), you will see around a 35-40% gain in horsepower and torque at your non-supercharged maximum horsepower rpm. If detonation forces you to use an ignition/timing retard system, you will of course see less of a gain because backing off several degrees of timing will greatly reduce an engine's power output. At higher boost levels, the heat generated by compressing air will produce diminishing returns as the boost is increased, although the use of intercooling or racing fuel can avoid this scenario of diminishing returns. Assuming the use of intercooling to run higher boost levels while maintaining reliability, a 100% increase can generally be achieved at around 17 psi on an engine with 9:1 compression running pump gas.

With Corvette mods to engine or components changed will most likely need re-tuning of your cars computer. Now I only say this because I have too since there is so many variables. This might not always be the case so do your homework. You should be open for it if you want to make a lot more power.There is many ways today to do this. You could do it yourself if you are willing to spend many hours learning at the expense of your car and your time and gas. Or you could take it to somebody and have them tune it for you on a chassis dyno. I would suggest this option because most likely they have a program already proven for your chosen performance upgrade. They will most likely use either LS1 Edit, EFI Live, or HP tuners. The next question is where do you go? Great places to go for Corvette mod's
Another great Corvette mod is a Camshaft! The Camshaft is the heart of the engine. Selection is crucial for optimal performance. Things to consider is how you drive your car? Is it an Automatic or Manual? Daily driver or race car? Comp Cams pretty much makes all the performance camshafts for all LS Gen III or IV series engines. Say if you bought a Lingenfelter LS series camshaft it would be ground and made to their specs from Comp Cams.
