(j. mcgrath said his tune fluctuated on his wideband by .5 with the elevation change reading leaner in albany than in placid. and we know “lean is mean”) i cannot speak as to rays numbers i wasnt there and i dont know what correction was used if any at all. i know rays supra sure as fuck had the performance to back that number up though. and my guess on doms sti performance is just that… a guess. wont know until he runs at the track… every dyno is set up differently but pete’s comment of the 1.2 correction factor gives me a bit of insight as to how happy the dyno was infact reading. --- _[View the full topic](https://forums.speedlife.net/t/dmpyrde-on-the-dyno-the-shop/251728)._
