Really took alot of time looking into this fuel management system due to seeing many strong reviews but a few disturbing ones as well. The big selling point was the fact that locally dynos here run $400+ per run and this system doesn't require dynos / progamming. Will post in a couple weeks my results. Going to install this along with o2 removal, Lloyds adj timing wheel all together. Already have factorry sstage 1 Cobra Tri-pro 2into1 / K&N intake upgrade on my 09 Vegas V100.
