I use a cold start valve from a 911SC as a 7th injector, plumbed in about 6" before the throttle body for good atomization, I use a MSD Rpm switch to fire it at 6,000, and that is wired to a pressure switch so that it will only fire at 6,000 RPM on boost. Simple cheap effective.
My A/R's would start to creep from 12 up to 13 around 6,000, now when the injector fires it drops to 11.5
