The Dyno Dynamics dyno is a true tuners dyno. It measures torque with an actual torque load sensor vs. the DJ which calculates torque by measure speed, rate of speed vs. a known weight (the drum).

We have dyno'ed a ton of bone stock cars which we all know have a "range" of rear wheel readings that we have been able to "offset" with the 12-14 % and lock the dyno at that reading. We haven't touched it since we bought the dyno. A bone stock C6 will make 345-355 RWHP and we see them in that range at the 12.5%. Again what's important is that it leaves with more!
