I just turboed my ls, and i know idealy i would go with around 450cc injectors with the HP im going to be making. So the dsm450's would work good, but whats the difference from going with the dsm compared to the RC? Theres such a price jump between the 2. So is there any pros to paying the extra for the rc's or should i stick with dsm? Anything i need to worry about if i buy the dsm's used with around 70k miles on them, or should the injectors hold up for a while?

dsm's you have to use a resistor box, and rc's plug right up.
