Nelson Tune questions
OK, after alot of research, I've decided to get an 89 Nelson custom tune. I have a couple questions about my truck's warranty and reliability however. If I take my truck to the dealership for warranty work, will the technicians notice the custom tune with their equipment? I ask this because Popular HotRodding magazine did an article about the Predator handheld programmer in an '05 Mustang GT. They said the OBD-II computer in the Mustang keeps a schedule of when the computer was accessed and changed. Is this true for the NBS GM trucks? If it is true, does a Nelson tuned PCM show the date it was tuned or the date my truck's stock PCM was originally flashed? Also, I plan on getting a 89 octane tune with the suggested amount of TM removed. Will this affect my truck's overall reliability? I plan on keeping my truck for a long time and I don't want to have any major, unscheduled maintenance issues in the future. How many miles have the Nelson tuned trucks at this website gone since getting a Nelson tune? Any info would be appreciated.

the stealership will not be able to actually see the tune. as for relaiability. that i believe is up to your right foot. not taking all tqm out is a good thing. unless certain steps are takin to help out the tranny. i would get the 89 tune now. nelson tunes are amoung the best. remember you get what you pay for and he is a sponser.

Kepp your factory stock PCM. Order a tuned PCM from the tuner of choice, Pay the CORE charge (if any) to get a new tuned PCM (keeping your original stock just incase)
Now when you get your tuned PCM, remove the cover (4 Torx head screws) and swap with your factory original. Put your tuned PCM in your truck. If you have a problem take it to the dealer, They will hook it up to the scanner but they will not see anything on screen to make them think its different. If they pop the hood and look (remember they have to remove the plastic shroud around the pcm) ALL THEY WILL SEE IS THE pcm WITH ALL OF THE FACTORY STICKERS AND SERIAL NUMBERS.
I think people are putting to much fear into this. People at the dealership don't have time to search for something that they can not make a judgement call on anyways.

BTW, the dragstrip near moncks corner is under new ownership and from what it appears they are serious about the place. Here is the link http://www.lowcountrydragway.com/
Its only an 1/8 mile track, but it is the closest one.
