I don't know much about PCM tunes. How does the Nelson tune work?. I would like to keep my pcm so I can allways go back to stock. Its a daily driver so I want it to be reliable. What kinda horsepower gain do you get with a 87-89 octane tune?

Nelson tunes don't allow you to keep your stock PCM. However, with that being said here is how it works:
-Fill out the online form that says what mods you've done to your truck and what you are going for (performance, fuel economy...).
-Someone will call you to confirm your order
-Nelson sends you a tuned PCM that you replace your stock one with
-Send stock PCM, "core", back to Nelson
This way your truck is never down while you are waiting on your PCM. Anytime you want to return the truck to stock, just call/email Nelson and tell them to send you a stock tune. You get lifetime retunes with Nelson so that all you have to pay is shipping of the PCM's. Pretty good deal if you ask me.
As far as gains, you won't be disappointed. I would go with the 91-93 octane tune and you could see 25+ in gains. It will be reliable no matter which one you choose.
OK sounds good. Do you just plug it in and play? What is nice safe reliable tune? How much TM to be taken off?
If a person wanted to keep his stock PCM, I believe he-she could make a trip to the salvage yard and get a core. I may be wrong though.Quote:

You remove your stock PCM (located on the driver's side next to the battery) and plug in your tuned PCM. So, yep, just re-connect and go. Nelson will send you a safe and reliable tune. It will remove TM, adjust timing, shift points... They have tuned 100's (if not 1000's) of vehicles from mild to extreme mod's. A wise decision to get your truck tuned by them.Quote:
