HP and Torque numbers for 3.6 Pentastar
 
I purchased the OBD2 bluetooth gadget on Ebay and I downloaded the Torque Obd2 Engine Management Diagnostic app for my HTC smartphone. I did input the vehicles weight, atmospheric pressure, and some other info about the jeep to get the proper hp and torque ratings. After running the app for several days and logging the info here are my best numbers:
Torque: 212.1@ t 4080 rpm and 203 Horsepower @ 6380 rpm at the wheels. Atmospheric pressure adjustment @ 3500 feet (12.8 psi), cold air intake temperature was 40 C. 104 F.
Keep in mind I do have a cold air intake system with a throttle body spacer and the Magnaflow catback. :thumbsup:

One more thing to add: the most useable Torque is when I drive about 80km/h (50mph) in traffic in low rpm and when acceleration moderately the engine produced 191 fp of torque (at the wheels) @ 1535 rpm which really contributes to an average of 22-23 mpg in city driving, but I really have to take it easy to get this mileage in the city :-)

Sounds like quite a bit of drop by the time it gets to the rear wheels.

Actually this is not too bad, I used to own a 2006 Jeep Liberty 3.7 and had it dyno tested the old fashion way on a Mustang dyno. the results where 156 hp and 168 fp torque on the wheels...

the driveline loss is in line with the old 25% coeficient reported for awd drivetrains. I was expecting smaller losses but then again whether it is an app or a dyno, it is relative.

Re: HP and Torque numbers for 3.6 Pentastar with the Diablo Trinity
 
I just added the Diablo Trinity and uploaded the 91 Octane map on my jeep. I'm trying a tank of 91 octane gas. Low end torque improved by about 20-25 fp,(on the wheels) but no increase in max torque and hp numbers yet...I need a quite road and good conditions to really test what the tuning can do. :lol:

Now, this is interesting. After driving with my Diablo Trinity for one week I get the following numbers with the 91 octane map:
Max torque: 255 @2223 rpm at the wheels (cold air intake temp 69 F.) Baro pressure 12.9 psi. Hp: 198 at 5585 rpm.

So your torque increased by 20% over the OP's usung 91 octane, but at lower rpm, how does this compare to his 212 at 4080 rpm?
