I don't think it should be called a "fail" until somebody atleast tries it. The Dragon Fire could be the greatest thing ever for an LT1. Just what we are all looking for to fix a weak link in our motors. But in the past their service has been horrible. I wish I had 300 bucks to try it.

Come on, they are claiming a 100tq gain at 5000rpms how blatant does a lie have to be before you are allowed to call someone one it?

It does note fuel and spark changes as well but for a LT1 to lose torque like that it would have to be horribly neglected and badly tuned and then the PROBLEMS corrected when adding the new part.

Actually, their graph claims other fuel and air improvements. Not just their unit alone. Im not a AI fan boy, but thats what it is. Im curious, but would worry about fitment.

Not sure why people complain of poor customer service I got them on the phone right away (which is a miracle these days) and they were more than helpful.

The stock Delco/Delphi stuff has always worked fine for me, the two unvented units I have had proved to be trouble free units. The first one lasted 10 years trouble free and was killed by the WP, the second was working perfect when it was pulled last week for a vented conversion. Once again went with a Delphi unit opposed to these sketchy after market units that seem to cause nothing but trouble. The optis are not the LT1 weak link, people who use junk parts, can't install things correctly and refuse to diagnose problems are because it's easier to blame the opti.
