I'm the same way, but at the same time someone has to test it. Unfortunately it's not the company or they have but are keeping the numbers a secret. If that's true then the numbers are 1: not good enough to justify price or 2: lower then stock. The latter I doubt. It would be nice tho to see how it effects the power curve. Kinda wish I had a 3.6 as I have a dyno shop i can go to. I know on my 3.7 I've picked up about 30rwhp and 40rwtq with bolt ons and no tune. And that could even be conservative.

If the company can't or won't then why should the end user? Beta testers would be ideal but I don't see any information that says they do or don't use them. Again, if the company can't provide data on a product, the end user should pass.

30rwhp and 40rwtq are impressive numbers for bolt-ons. Providing you're replacing major components like cylinder heads, camshaft and/or intake. If not, I would have to see dyno graphs to get a better understanding how that is done.

All stock heads and internals. Power was gained simply by improving volumetric efficiency.

Ive replaced the intake, throttle body, and ported the intake manifold. Its got a full headers back exhaust, larger injectors and a catch can. On the stock tune no less. I am working out a day to get it tuned on the dyno but the military is getting in the way again lol.....

Anyway the 3.7 is known for making as low as 155 rwhp in the liberty to as high as the lower 170's. Just depends on drivetrain. Mine made 192rwhp and 213rwtq with a really broad power band.

As I said before I wish I had it on the dyno stock to see what it did stock. And for every mod I've completed.

To put that power figure in perspective tho Ajag's 3.6 in stock form made 185awhp

Any dyno information on what a stk. 3.7L makes in a Jeep Grand Cherokee? As you said, you didn't get a chance to dyno the vehicle when it was stock. Having that data would be helpful in determining how much power was actually gained by your modifications.
