What are some good intake systems for the 4.8L other than the K&N and are there any superchargers that will not void factory waranty?

 

Superchargers dont void your waranty but any damage as a direct result of the supercharger would not be covered.
The Radix Magnacharger is a complete kit and they waranty engine and driveline (correct me if I'm wrong) if you use the stock pulley and tuner and don't alter it.

 

same here on the radix

some intake companies are, outlaw, volant, aem, fram, GMPP, k&n, airraid, etc.

fyi the radix comes with a dropin K&N filter for your stock airbox and comes with a new high flow tube as part of the supercharger induction

 

radix still dont make the kit for the 07 yet ....i am waiting on it for my truck

 

Does anyone have any idea when the 07 radix kit will be out?

 

pm blownchevy, but if im not mistaken the ones for the 07 4.8/5.3 is already out and the 6.2L is only a couple of weeks out, already on preorder

 

What about a programer for the 07s is superchip the best one and how much will it realy improve power?

 

dont get a programmer, its useless pretty much. search for a mail order tune

 

Where do I look I searched online and only found a couple for LS2 or L98, do you have one on your truck?

 

not yet but i plan on trying to get a dyno tune, even better than a mailorder, i meant to search on this site. see nelson performance, wheatley tuning, wait4me performance, etc. search for threads on mailorder tunes
