for instance. if you run 87 octane in it after running 93 octane it will ping a little when you get on it. after that the pcm will switch to the lower timing tables. allen will have maxed out the lower timing tables for it to still run well. then when you put 93 or 91 back in it will be able to go to the higher tables.

the 91 octane tune is--the high octane tables have the timing turned up to get the most power. it is the same on the lower tables. it's a little less perfp when you go to the low octane tables but it will still run pretty good.i have a 93 tune. i have put in 87 octane for a couple a trips. since i do not have the dual octane tune it would pnig if i got on it. as long as i was cool with it it worked fine.

All the satisfied Nelson cutomers made me go with him but now that I have the tune I dont know what I would do if I didnt have the free updates. I mean email/call Allen and tell him what your doing and within a week(thst the longest its taken for me) you will have a new updated tune. I think I gained like 20+-Ill have to go look at the dyno sheets!
Oh yeah about the shiftkit- After I tried to call KDS for 2 days straight every 30 minutes and never got even a answering machine I call Jagperformance.com who is actually right next to Nelson and I think they are good friends as well. Joe & Jag has a kit put together with the Transgo shiftkit,Vette servo,and a few other parts that you need to replace when your in your tranny(like aluminum accum to replace the stock plastic one) for $151 shipped. I went with them because he and his wife were very very helpful Plus I like having everything I needed already put in a kit!

Got my Nelson tune in today. Haven't driven it much but from what I have driven it from about a 35mph roll when I stomp it it will chirp the rear tires every time. It will be later tonight or tomorrow before I get a good race goin to give me a little comparison. Customer service was great from Nelson definately recommend him.

Will have servo and shift kit done as soon as I get around to ordering them. Whats the best place to order them from?

untill you want more again.

You will gain mpg's with a tune. Remember economy is a bi-product of effeciency.
I have the Nelson 91-93 tune with all tm and speed limiter removed. All stock except for LT1 fans, K&N replacement filter, vette servo, and billet overdrive servo. I have never been to the track or to the dyno but the "butt" dyno is telling this thing is a completely different animal. My rpm's use to slowly climb to 5200 before shifting at WOT, now they scream to 5600-5700 then snap into second gear, then 3rd, then (I never got that far).
Another big defference I noticed is when I have the cruise control on. I travel the same stretch of highway everyday coming home from work and I encounter this 6% grade of a hill. My truck use to have to kick down to 3rd gear to maintain cruise speed w/ the factory tune but not with the nelson tune.
