    I’m looking at some point to tune with GearHead, don’t have the money for 93 or locations for e30, I was looking at the 87 or the 91 tune, does anyone have these tunes? What is the HP/TQ increases, 0-60, 60-100, 1/4 mile times, and MPG? I’d like to keep the MPG around 20 if that’s possible, doing a lot of daily commuting.

    You won't lose any fuel economy of you keep your foot off of the loud pedal.

    Matt is 100% correct. My tunes have actually increased my mileage if I keep my foot off the loud pedal.

    As you can see in my sig, I run a GH tune, in the trip below I was running the AO tune because I wasn't sure if I could find ethanol.

    It's a SUPER tall order, but when I have kept my foot off the long skinny pedal and just set the cruise, I have gotten 32.3 MPG on a 200+ mile trip. But that's also using adaptive cruise set at 65 MPH, because there was too much traffic to fly down the road anyway (two lane), but the moral of the story is if you can stay out of the boost you can get good mileage.

    What's keeping you from going 93 octane?

    I’m getting 19MPG of mixed driving ( driving mostly just “going with the flow” of traffic and very few of any WOT’s ). I think the spark plugs are gapped down too much causing the decreased mileage. Shop I had install them said they had them gapped at .021 instead of the .028 or so that they were supposed to be gapped at. They claimed it would be fine gapping them like that and they have done lots of work on these cars and the most I would see would be a decrease in MPG. So ‍♂️

    Money, I don't have a job right now, my parents don't want to spend the extra money on 93, once I can have a job, I'll probably run 93, until then, I'm stuck with 87/91. More likely 87.

    I'm running 93. Cost difference is less than 3 bucks per fill up.

    I fill up once per week, so that's approximately 8-12 bucks extra per month. Which is less than 200 per year.

    For me it’s like $12.80-$20.80 difference for each fill up, 93 around me is like $0.80-$1.30 more than 87. So that’s a minimum of around $768 more for fuel since I fill it up around 5 times a month.

    That's significant.

    Do you have a Sams, Costco, or BJs near you? They tend to only have about a .50 cent difference between regular and premium.

    The closest one is roughly 35 miles away, wouldn’t be too far if it wasn’t in the heart of Austin. It’s too far out of the way for my daily driving. Thanks for your help though.

    That sucks.

    If it makes you feel better, id love to run an e30 tune, but I can't, because there's no e85 in all of Connecticut.

    Same, the only place for me would be Sunoco in town. Haven’t seen it anywhere else...

    My 2011 with SCT tune, CAI, and noisemaker delete, running on 93 (SCT is set for 91) routinely gets 27+ on highway trips (I've seen as high as 30, but only briefly) with the adaptive cruise control set 7-12 over.

    Thanks, is tuning with the SCT tune pretty straightforward?

    I average 21-24 mpg with 87 gas(winter), 21-25 mpg with 93 gas(summer). lots of highway driving. (19,500 miles since Jan 1, 20)
    HP/Torque went from 318/320 before tune to 339/415 after tune, plugs, 3 bar MAP, plugs, and GH intercooler

    It's been straightforward to me. I have to set it back to stock before Virginia emissions testing, because the test doesn't see the two rear O2 sensors (with the tune) and therefore returns "fail". But it's easy to restore to stock and easy enough to retune after passing the test.
