Hello, I am looking for some advice about stacking power boxes on my truck. I would like anyones input on which boxes to use, tranny slip and limitations, and an educated guess on what my truck would do on the dyno.


My truck is a 03 GMC crew cab sb Duramax/ Allison, Edge 4.73 with Attitude monitor, AFE intake 4 inch exhaust with Aeroturbine muffler. 14.8 quarter mile and 0-60 in 6.2 according to the monitor in stage 5 125hp setting defueling the 4-5 shift only. Also , any one know the accuracy of the Edge performance meter 1/4 mile, is it similar to 1/10th accuracy of a Vtech? Any comments or suggestions would be appreciated!

yeah, you want answeres, talk to someone in the know.


I am not an expert, and SOCALDMAX is even dumber(if that's possible). ask anyone else but us (PS. a hamster has more brains than the 2 of us put together)Edited by: Got Juice?

Unless you plan to spend some $$$ on the transmission, don't do it...
