Depends upon who you talk to. The above is the difference in ignition advance I measured on a M-Coupe with the Shark Injector at WOT.
They have been dyno tested with varying results but I haven't seen results from a dyno I would consider fair and properly performed. I do not mean a dyno tested like Jim C. recommends. I mean things like the amount of adaptation that occured in both states, fuel quality, proper cooling and so forth. This has been discussed heavily on the M3 board by Dpeete, myself and others.
