I've done it, no problems here. Just be 1000% sure the bolt is back in and in tight. I believe ChrisD has done it as well, and he was pushing a lot more power through than I was.

I used to do this often, no issues. I never pushed beyond 330whp on a dynojet with a bad alt adjustment. If it was me I wouldn't push past 400whp in this method, Id find a AWD dyno as the loads for tuning may be more accurate. Good luck

With a good dyno they should be able to add extra load to simulate the AWD, at least somewhat.
