Unless you're under warranty, there are more affordable choices that will net the same gains. If you want an intake ($150 AFE on ebay) or exhaust ($50 x-pipe or two $18 mufflers on ebay), hardware gains can be done for far cheaper than what $teve charges. Software can come from Powerchips, ESS, or $$Dinan$$ for whatever hardware mods you do. Buying $$Dinan$$ is just like buying BMW...it's for the name, but it's not like they're over there reinventing the wheel.
Short of going FI, nothing $$Dinan$$ sells justifies it price vs gains (if any) in HP. If you're looking to go FI, there are alternatives to them as well (VF, ESS) for sometimes HALF the cost while using the
exact same supercharger...just different software.
Or you could just buy the badges on eBay...you'll probably still net the same HP gains doing that
