If I buy a set of Cams (I have no idea who from yet) what would be the benifits from them? What HP/TQ will I get? How will it effect daily drive? How much do they run? Will I HAVE to get a tune for them? Etc.?
The Crower stock replacement cams don't require a tune, but are not an extreme change to the profile (great for small turbo IMO).
Anything else really needs a tune. You can get away with just cams if you choose one of the stage 1 cams and keep your rpm limit at stock. Stage 2 cams and above require heavy duty spring kit. Any of them would be much better with exhaust, and either a ported stock TB or aftermarket (best) TB.
Tunes really help out a lot. My SCT is saving me money in gas- although not enough to pay itself off- it was still a good choice to have for future upgrading.
