After he had removed the Jet-II, did he reset the computer as well? This
person DID have the 180 T'Stat installed...right? What did the power curves
look like with and without the Jet-II? Did he send the results into Jet for
an explanation? Can you have this person scan his Dyno sheets and post them
somewhere?
It just seems strange when the driving characteristics of the vehicle with
(and without) the Jet are very noticeable. (Better with the Jet...in most
cases.) Most of the people that i've spoken with (mostly V6's) have had
great results with it installed.

I'll tell you what happened during the dyno day a couple of weeks ago.
I won't draw any conclusions, just relate the event. A guy put his V6
Dakota up on the dyno, the only mods he had I know of was an MSD 6A
ignition and Jet II. He did the run. The graph showed a whole bunch
of funny spikes, and the hp results left a lot to be desired. I don't
remember the numbers, but the owner was disappointed, and I remember
the tech who was running the dyno saying the numbers didn't look good.
When the tech asked what mods the guy had and the owner replied, the
tech reacted to the Jet II rather negatively, and told the guy to take
it off. He did, and the next dyno run showed a smoother curve and a
slight increase in horsepower. The tech said the Jet II's are junk
and he's never seen his dyno show an improvement with one in the three
years he's had it. I have no opinion on this, just relating what
happened.
