My metering unit had no mods and with fith injector i ran 250 no problems at all. I highly reccomend this kit to anyone and believe it or not it is so easy to fit. My electrician charged me 20 quid to fit as i told him exactly where to splice and solder.
I had the same mod with about a 24psi spike - no probs at all, drove to Le Mans with it this summer
Still have the full system if anyone is looking for one, as have had new management put on now
