1st, yeah depends on what type of dyno... Dynojet's are pretty much in the most popular. a lot of other lower/higher returning dyno's even have a program to convert your results to what a Dynojet would've read. as for running rich, yeah that's really normal w/intake & exh mods w/o a tune. your stock ECU over compinsates for all the added flow(stock, our engines lean out at higher RPMs).
