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.
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 :-)
