Was wondering how laser cut delivery valves work with stock injectors. The auto is about to get done and I figured i would have the pumped tweaked whille I was at it. Smoke isn't a problem, but how much difference will l/c's make on the stock injectors. Wainting on the injectors for a while. Also who builds the best laser cuts and what will they run me. And how much difference will these dv's make on egt's?
