Got my @BlackBearPerf tune yesterday and so far I'm pretty happy with it. Shifts are firmer and deeper into the powerband, and I don't have to beg it to downshift anymore. I can't tell a huge difference as far as the engine goes, but it definitely feels a bit more eager to get up and go. Not sure how much of that is due to TCM vs ECM, but either way it's noticeable. I also got the factory speed limiter removed and did not exceed the posted speed limit on a major interstate highway by approximately 55 miles per hour because I always follow the law. Anyways, big thanks to Justin and Jared. Very happy with everything. I'll update later with regards to fuel mileage and that sort of thing.

Oil change day. Right at 5k, added a quart at 4k mainly because I was towing for a few hundred miles. It was in the middle of the dipstick so I could have left it. Approx 8oz in the catch can, this is the first change with it in place so for now just a baseline. Not bad consumption for 225k in my opinion.

Refilled with 5qt Supertech full syn and a bottle of full syn Lucas with a K&N oil filter.

Not the best pic but you get the idea.

Best mod I've done so far.
