I'm tempted to leave the stock cam in it as I'm happy to keep under 6k, even on the track. Also, if I can find a system that can bolt up to the factory exhaust then if I get pinged for emissions I can swap back easily.if u want to pass emissions with a blower and cam u need the LS9 cam it does a decent job for factory, using the factory LS cam will work but does drop of quick after bout 6k as u just cant get the exhaust out so it just bottles up and kills power, the LS9 cam with the 230 exhaust lets more out which is why it helps, i had some cheap metal cats that lasted for years without issues boosted and would still be going if i didnt upgrade exhaust not sure what brand they were tho, also mounting cats further back will help them survive the heat (but may not pass tests) e85 will help as it has much lower exhaust temps
Q: Is water/meth still used to reduce IATs on FI applications?
