What ratio does my votech fmu needa be if im boostin 8psi with stock injectors? Help please

do ~50-55 at idle and 125 under boost. when boosting keep an eye on your fuel pressure, a/f and egt. If you dont have all of those gagues i suggest you install them all before you start to tune your fuel system. and rember its always better to run rich and slowly lean it out to a good median. running lean under boost can almost instantly destroy your motor. check out corbins write up on fuel injectors here http://www.2gnt.com/www/corbin/chooseinj.html .

i think he's asking about ratio which would be 8:1 disc

You might consider getting the FMU disk assortment from Vortech. P/N 6Z270-010. That way you could start at 12:1 like the Star kit and work your way down until you find one you like.

What he said. Start high and go down. To be safe U probably wont end up going below 10:1.
