it feels great, but have you run it on a dyno yet? i don't mean for power, but for accurate measurement of a/f ratio? stock o2 sensor only reads around stoich and you need a wide band to get true readings. i have a rrfpr on with 30# injectors. yes, it has smoothed out the power curve for high boost applications. but, i have had mine on a dyno and the a/f curve to show for it. actual applications of the rrfpr and 30# is exactly as dr. boost explains. at wot, mixture goes rich until about 3500-4500 rpm where it is around 12 or so, then it continues to lean out to redline. increasing idle pressure only adds more power robbing fuel down low, and washes things down. and, since eproms aren't available, unless dr. boost can enlighten us on c900 fuel curves and reprogramming, aftermarket system is the only way to get things right. only a couple more weeks for me... :)
