safc tuning

ok im runing an safc and dsm 450cc injectors for my turbo setup
and im in southern ohio so there is no dyno around here
with only 8 psi do i have to dyno tune it or can i set it myself

You can set it yourself for now but try to get it on the dyno ASAP. For better reliability, better power, and for many other reasons try to get it tuned quick. Don't think that you can just bolt on the kit and get away with it, if you want your turbo setup to be a good one you must TUNE.
