I'm sure justin can get it where it needs to be with the data log i sent him.
14-15 isn't bad. I'm sure it does need some tweaking since its sways to the 16-17s. Even that lean it won't hurt anything.


Do you happen to have efilive? If so would you send me your base tune? Curious to see the phaser tables

It has less from a dig than it did with just headers and tune and even less than it did stock. With that said it chirps em from a dig and then the rpms get up and it starts to spin through 1-2 shift and I believe it chirped into 3rd (could be wrong, didnt drive much).


I'm from Alexandria but I live in Anoka now. Where you at in the TC area?

Nice, I actually went to Alex Tech for part of my schooling.
I work in Anoka currently but live over in Ham Lake.
