I am by no way saying that GM's PCM's are going to be the most efficient and put out the most power. I'm just saying that they will optimize for the higher octane but not fully.

You can, but once you go to WOT with a tank full of 87 on a 93 WOT tune you will have nothing but knock. so to make that work you would have to have two separate tanks one for cruise and one for WOT. So it makes no sense at all to do it.Quote:

Crank relearn can be performed with a tech II or tuning software, its takes about 5 mins to perform.
I don't have access to either, so I guess a tune isn't an option for me. Sorry!Quote:

The local parts store should a tech2 to rent you
I had the crank re-learn done at the local stealership for free, at most they will charge you a small fee. They plug in there tech2 and rev the engine a few times and its over!!! Get the Nelson 93 tune, you will make up the difference of price per gallon with better mpg. It will take a few heat cycles for the pcm to learn, but when it does, Hold on!!!:burnrub:

I didn't do a crank relearn when I got my Nelson PCM.Quote:
