    Just had my car on the dyno after the header install. She made 442 RWHP. (Just ran on the Dyno, not tuned.) My tuner stated that we still probably have remnants of the winter blend gas. He also stated that with a proper tank of 93 I should be up about 10HP. My question, who do you think has the best 93? Thanks!

    I apologize as I don't know specifics...There is definitely a difference in winter and summer blends.

    Yes winter and summer blends are different. I've found Costco to be the best I've used. Shell #2.

    Costco, that's interesting. What do you guy's think of BP?

    Yeah. Tuners like it too, and it's around $3.30/gal while everything else is $4+. BP is fine. Nothing bad or particularly good I've ever noticed.

    Shell or BP only for me. Back when I had my built Lightning, it would run like crap on anything but them.

    According to Alex at Lund, Costco gas is crap and pulls timing. I love Costco gas strictly for the price of 93, never recorded data logs with it though. Has anyone actually data logged Costco vs Shell vs BP vs Mobile to see which ones pull timing? I'm sure it also varies station to station and region to region as well.
