OK OK I kno this has been asked a million and 1 times but what is the OPTIMUM numbers to set the HPP3 to on our 2002 4.8???

Fast4.8??

 

OK OK OK.....

I have my 2000 at ..
+4 on the 1-2
+12 on the 2-3
+6 on the 3-4 ( which you really don't need for the 1/4 mile)

93 octane
shift firmness on
160* tstat ( if you have one )

 

Greg,
Are you actually using 93 octane gas? I use 87 on mine. Is it ok to retune for a higher octane?

 

Where do You Have the Rev Limiter set at???

 

6200 for the limiter.

Where I get gas, we don't have the reformulated stuff, so it doesn't hurt to run a 87 tank or two. Usually I run the 87 when I'm going to work on my 6 out of 7 set(95% highway driving).

And yes, 6200 for the rev limiter.
