HEAVYdutyDMAX 08-26-2007, 08:18 PM I have been running the Hot J/A for a couple months now and i am really happy with it, espacially the mid - upper range. The probblem just seems like i have no low end power. Is this typical with the edge, i know it is getting fuel because it smokes like crazy but it just doesnt feel "snappy" at all? Please help! Thanks. Siphon 08-27-2007, 03:50 PM I think it's an inherent limitation of harness box modules. Their means of overcoming the torque management program in the ECM is limited vs a reflash, simply because they operate by tricking the ECM with signals from the sensors instead of just rewriting what's in it. Someone with more knowledge from time spent with EFILive could confirm/deny.

Yeah,send your VA box in and have the 220 tune loaded into it :D . HEAVYdutyDMAX 08-28-2007, 02:13 PM Yeah,send your VA box in and have the 220 tune loaded into it :D . Haha ya i thought about doin that, but I tried contacting VA a few times to get it upgraded but no one would ever answer me back so i went and bought the HOT edge. I like it a little more but just a little weak down low... 01Duramax6spd 08-28-2007, 02:24 PM Haha ya i thought about doin that, but I tried contacting VA a few times to get it upgraded but no one would ever answer me back so i went and bought the HOT edge.
