I know, get a Nelson tune! I probably will but wanted to do this first. I got a used HPP for a pretty good price and think I can actually sell it for more than I paid for it if I put it on Ebay. I'm going to run 91 oct gas (highest CA has)and run my old HPP settings (+3, +10 & +10) for shifts, 93 tuning and firm shifts. Predator tune was +3 on spark, PE was zero, shifts were 1-2 5880, 2-3 5820 and 3-OD stock, -25% on shift quickness & +25% on firmness (quickest & firmest possible). I'm going to log MPG, 0-40, 0-60 & 0-90 times as well as 40-60 passing times. I want to run at least two-three tanks of gas and get 10 performance runs in to compare. I'm also going to use the Predators "live data" mode to check the O2's, LT's and if there's any KR with the settings. What numbers should I be looking for with the O2's and LT's? Is there any thing else I should look for in the "live data" mode? It'll take a while to do this, at least a month (fill up about once a week)? I'll report my results and driving impressions for each programmer. In the mean time, saving for a Nelson tune.

Ahahaha, that's what I do....buy low and sell high. Man I love the pure capitalism on ebay.

BTW... what if you picked up a used '00 PCM so that way you could sell the existing PCM you have w/ the Predator on ebay?

 

Hmm, idea! But wouldn't a different PCM have a different VIN? Would that matter if I every sold the truck or traded it in?

Um... Got me.

 

When you get a mail order tune.. they send you a new pcm... and you send them your old one.. i wouldnt think it would matter...

 

I think they put your VIN in the new PCM so it's still stays the same.
