Duramaxamizer?

[05_LLY]

I buddy of mine just bought a 03 duramax/auto truck. the truck came with a edge juice and a DMaxamizer on it. Upon playing with everything we cant notice any changes turning the maxamizer up and down. We even tried unpluging the edge and just running it with the maxamizer and still no difference.
I can only find two plugs on it and they are both pluged in. Are there anymore im missing? Should it give a noticeable gain?

Thanx,
Caleb

It definitely did on my Dad's '02, with & without a programmer...IIRC, there's the "Y" harness on the firewall and another connector that plugs into the power distribution block under the dash...

My buddy has the D-maximize4r stacked with Edge and PPE loadrr and it's a screamer.. He run's the PPE and D-maximizer only now becuase of the timing issue, but yes it makes a big differnece on his 2003 as well.. Somethign must not be hooked up!!!

The duramaximizer makes a big difference, with that kind of tuner, something isn't right. I put us aabove 600 RWHP.

I have one on my 04 lb7 and I can't notice a difference either. It does make that clicking sound at half throttle so I think it hooked up correctly.
