Yep, I've done that as well, but second gear on flat road doesn't apply enough load to get a true representation of low-mid range torque since the turbo spools later. In general when you do this on a chassis dyno, you apply more load than the car would normally see in second gear to get a longer pull and a more accurate representation of the power curve. The other problem is that when you do a shorter pull like that, the road dyno's resolution is significantly reduced and further reduces the accuracy. You also have to consider the torque converter which allows for some degree of slip and creates further problems when trying to get an accurate dyno. That's why I don't even bother trying to get numbers for AT cars with the road dyno software.

From the boost, a/f, ignition advance, and air flow the car was running, I'd estimate it to make ~210-215whp and about the same torque. This tune was on par with other cars I've tuned with similar setups, so overall power levels should be similar as well. Of course these are estimates, so take them with a grain of salt.

Overall, the feel of the car and the drivability are much more important to me than peak numbers anyway. This customer felt the same way so I didn't feel it necessary to try to get some sort of graphical representation when I knew it wouldn't be nearly as accurate as I would like.

Thanks
