Hennessy Performance or Renntech

I just wanted some opinions...
Which upgrade mod sounds more appealing: Hennessy Performance E55 Performance upgrade (www.hennessyperformance.com), Renntech Stage 1, or Renntech Stage 2. I dont know much about any of these upgrade packages, and Im not seriously considering on planning on getting one any time soon, I'm just curious what you guys think is the best investment if I do decide to go with an upgrade kit. Thanks!

Think you meant: http://www.hennesseyperformance.com/...eyperformance/

Forum members seem to have had the best luck with Renntech, Kleeman, and Evosport - take your pick - all seem to offer high quality, well thought-out packages.

As for Hennessey, take a look at the profile from one of the Viper organizations: http://dodgevipers.tenmagazines.com/hennessey.html.

Hennessey does not have a stellar reputation around the car club communities. He has been known to cheat a lot of people out of their money and vehicle. I would stick with Renntech personally.

Yup me too!!

I have Renntech Stage 1 and I love it! I'm sure the other tuners are just as good.
