I ran the crap out of Dmax with an Edge Juice 4-setting box. Highest setting gave me 90hp and 250ft-lbs and woudl let me spank a Mustang GT and hang with a Z28. Most of the time I ran level 2. I didn't have gages so I don't know what kind of boost I was running though. My uncle has had 3, '01, '02, and '05 and has not had any problems with any of them. Point is I never had a problem with mine and haven't heard about them being an issue. But I've been out of the loop on the Maxi-Pads fro about 4 years now so I can't say for sure.
