    Yeah, canned tunes run pretty piggy rich.

    There is lots of head room you'll see once you pick up a WB and your face goes like this -->>> O_O

    When you see it sitting at a solid 10.5:1, lol.

    Look into lean burn cruise tuning as well...lots of good info out there if you planning on picking up tuning yourself down the road.

    I'd also say a 3.5" is the best bet.

    And why? Because I'd rather run a larger pulley with a leaner AFR and more ignition timing than a smaller pulley with a richer AFR and less timing.

    Then again, a 3.4" and a 3.5" won't make that much difference...but a 3.3" to a 3.5"...yeah, that'd help quite a bit.

    Thanks. I live in the middle of nowhere in northern MI, so If i'm goinging to get a custom tune i'll have to do it myself... Was planning on a wideband soon to tune in my truck, its caburated so no computer involved there...lol then i'll put it in the grand prix to motivate myself into getting a programer...


    once again, thanks for the information.
