I haven't tried their Comp box but do recommend that you speak with Diesel Dynamics about their rebadged Edge products built to DD's spec's. DD understands the Cummins ISB and how to test aftermarket products. Also call Chip at Blue Chip, he pioneered the fueling box and has tested several boxes He may recommend a different brand for different a application such a an ETH or your ETC engine. He sold more then one brand the last that I checked. Some companies can't even tell you how much their product advances timing and timing is very important as you add further mod's such as injectors, large turbo housings, tow heavy loads and (especially)use propane. I'll still try new products as they become available but I've had no problem with my Blue Chip/Diablo Puck and I know that Chip will provide great service and updates.
If the Puck or EZ will be your only engine modification, you will be happy with either of them or several other brand of boxes too. Sorry for the rant but JMHO and hope this helps.![]()

you can call dd if you want, but edge programs the box for them. the timing is the same in the 2 boxes. chip does know his stuff, but i tested a edge comp box vs a fms blue box.
the edge comp made 10 more peak hp. but at 2200 rpm it made 84 more hp. i always try to have the best products on my truck and i'm always trying new things. so far the comp gives the most hp. and it's the least expensive box.

my only experienece with the puck is on my friends truck. he and his dad both bought new eth's one had the puck, and the other had the ez. they race all the time and the ez was outrunning the puck by 3-4 truck lenghts from 50-100mph. so he traded the puck in for a ez and now it's a dead race. maybe the puck wasn't working right, i'm not sure.

take that $100 you are saving and get the comp. it gives you control in the cab, and when your ready you can hook up the pump wire. unless the ez is as far as you will go. i started with the ez and it's been all downhill since
