here's a post made by Allen on another site, only goes into a few of the things he can do when tuning:
I'd like to list a few features as well.
-Dual octane tuning is available and has always been available. Dual octane tuning allows you to take advantage of both sides, economy and performance.
Options for dual tuning range from 87-93.
-A Performance 93 tune will give you the most gains. Expect a nice drop in your 1/4 mile times and possibly better gas mileage to offset the need to run lower octane.
-When 93 isn't available, 91 octane offers similar results. A great increase in power and great drivability.
-The higher octane the PCM is tuned for, the more performance you'll see. For those who run 87 octane, you won't be left out. A custom 87 octane tune is far superior than a stock tune; so expect great results.
Torque Management: If this is in your special requests then this is for you. TM is supposed to prolong the life of the trans. If this is removed completely, your trans may fail. However, if you have a built trans, this is usually removed to keep the truck from falling between shifts. I've seen stock trans with no TM last a long time and I've seen built trans break with TM, so it's your call. If not mentioned, I'll perform the normal trans tune and leave about 30-40% TM in the PCM. This is still a nice feel over 100% TM.
Before PCM's are sent out, I flash it with GM's latest calibration which includes your VIN and all options. Then the PCM's receive the custom tune based on your modifications and requests.
It's no secret, not every tune goes perfect the first time (most of them do though). This is with every tuner out there, you know who they are. So, I'm going to ask you guys to check your service number. You'll need to view the top of the pcm. The PCM is located next to and below the battery. Remove the plastic cover on top of the PCM by releasing it from the two tabs. Then, unclip the metal clip holding the PCM to the mount. The PCM is now free. The service number will end in 4896, 411, 605, 242, 106. I stock the most common PCM and the 411 should be compatible with all 99-02 trucks and the 605 for the 03/04 trucks, but somtimes that doesn't happen. This will help get your tune right the first time. I should be able to send you a 411 PCM and it should work the first time for your 99-02 truck but thanks to GM about 1% may not. ( i know the little secrets that are supposed to make them work, but sometimes they just don't).
When your PCM is installed, I ask that you return your core within an acceptable amount of time. I do offer the option of keeping your PCM for $120 extra (in addition to the cost of the tune).
