Find a Tuner that will work with you and see if its already been tuned. EFI Live and HP Tuners can compare the OEM Stock tune to what is in the PCM now and the tuner should be able to tell you if its good or bad.
Reguardles. Before you do ANY tuning, I would change the O2 sensors, clean the MAF, new plugs nd clean the throttle body. That way, you have a KNOWN good baseline if it ever starts running bad.
For instance,,, If you tune on old faulty O2 sensors and one or both go bad, you insert new sensors and now the tune is no longr accurate at part throttle cruise.

That is good information from all you guys! I appreciate the help. I will keep everyone informed and once I do the tear down and build up I will make sure I take picts. I was running some tests on it tonight and about 2000 rpm then ease off the throttle you could here a lifter tapping around the #7 cylinder under deceleration and steady on the gas.
