Oh yeah....and can I run one of these without tuning on a stage one computer and injectors on a stock fuel system? I am looking at the GT3071R and the 3147. I am leaning toward the 3147 because of price....
I believe AGP has a turbo selection post in their section of the forums which may help you decide. Both turbo's will spool fast, but the GT3071R will make slightly more power. You can slap the turbo's in without tuning as long as you keep the boost down, if you want to turn the boost up to unleash the actual potential of the turbo you will need to upgrade your fuel system and get a tuning device (piggyback, standalone) and begin tuning.
