Is this for real, or just another example of false adverts?

that is what happened on the HorsepowerTV show last weekend....
They repeated the numbers shown in this graph, almost exactly.

But they also stated, besides not working on unfixed "tick" cars, that HyperTech did NOT recommend using it on cars with exhaust and CAI mods,

However on HyperTechs FAQ it states:

"Hypertech Power Tuning is calibrated for stock or near-stock engines (engines equipped with high-flow air filters and cat-back exhaust systems)"


So which is it? I have the CatBack now, and the K&N on its way... would consider doing this, SCT, or Predator, but not if they recommend against it.

Dude, I just saw your post... I just got one of these last weekend for my 03 Cobra... WOW! Best $369 I could have spent... I only have the stock pulley at this point, but the difference is very real... not only in HP but in low end torque too. For the price, you can't beat it and it's easy to install. Hypertech has been around for a long time... they know what they're doing. I love it! Good Luck.
