    Ac kicking on will bump the idle of the car a few hundred rpms unrelated to air off the fans

    Yes, but what I'm seeing is excessive surging and the idle rpm never stabilizing. I'll try and get a video of it

    What’d you set your idle to?

    It's set to 950-1k.
    I tested the theory my tuner presented by turning on the AC to trigger the fan, and watched STFT respond to the extra air flow. I then blocked the fan shroud with cardboard and found STFT to flatten out quickly. So I ended up with this to correct the problem.
    More room for stickers, perhaps?? LOL[​IMG][​IMG]

    Not the best video. It'll do for now.
    We just got the SS map dialed in. Had to drop boost from 30psi to 27psi. I was consistently getting a few degrees of KR on 91. We're about to tune on e85 mix though

    Dropping the tune down to 25psi. CA 91 octane sucks. We're on our 8th revision trying to get rid of this KR. The car is begging for more octane. I can't wait to start on the e85 tune to really kick it up a notch or two!

    I also just put my order in for a new set of Fortune Auto 500 coilovers with 9k fr, 11k r hyperco springs. It's about a 3-5 week lead time currently. My Cobb springs and Bilstein B8s are just too damn soft to have any sort of fun with my current wheel/tire setup

    I was in BFE & had to fill up on 91 & remapped with OST stage 1 map & it guzzles fuel, but it drove pretty damn good yesterday & today.
    I’ve hit about 300 miles on the tune, but that 93 alone is JUICE
