Any good use for this stuff....
Any good use for this stuff.... I was going through some of the LS1 aftermarket companies and in a couple I saw the "V-plus volt booster" and the "SLP air temp module." Are these worth the money? It's cool the have your alternator pump out a little more voltage (v-plus) but is it needed? If the SLP thing will give you a few extra hp, then for $25 it couldn't hurt but does it actually make a difference, or at least a difference that you can't do with hp tuner if you've already got that? These questions may sound silly but I don't hear much about either of these products so I'm curious as to what the deal is. Thanks.
