Going to the track tomorrow. Previous best was 14.8 at 91.

ps.next mod--N2o kit.

 

If everything goes good I'm thinking maybe 14.50s

Boost is an addiction. Once you have a little you want alot more. Your next "fix" is just a pulley change away!

Good luck!

Give the sucker some more timing try 3-4 More degrees ans see if you get any KR when you add timing
with the Colder weather and good Gas 4 degrees of timing is Very noticable
Give it a try and see what happens
throw a little splash of 100 octane in and have some fun

 

Try to hit 15deg. I know the whipples come with an average of 15deg w/6lb. without an intercooler though. You might be able to get away with it.

 

Sounds good, I'll try it. Which tables do I modify to add timing? Should I add 4 deg across the board, or just in the upper rpms?

Thanks guys.

 

across the board will be fine it'll give you some more Zip down low for sure

oh Forgot you will be able to hit 15degrees for sure that is where I'm tuned at
As long as your using 93octane of better you should be there
Now go take it out for a spin with some More timing
What year is your truck ?
the reason i ask is that on my 2002 My Kr sensors suck !! we heard pinging before anything showed up if ever on the tech 2

 

Only 91 octane avaliable here in Utah. Mines a 2002 also.
