    A question about 87 versus 93 octane and engine performance

    Woke up this morning and everything was back to normal. I put a shot of STP octane booster in the tank and filled up with 93. All good so far. I should have mentioned yesterday that it was very hot (98) and my AC is out due to a bad condenser. Perhaps the temps combined with something wrong with...

    A question about 87 versus 93 octane and engine performance

    I have a 2015 sonic turbo sedan with the Trifecta tune package. Fabulous tune and it really puts some get up and go into the car. I had to drive to DC today (I'm in Pittsburgh, PA) and yesterday I was down about 1/4 tank and I hesitated to do it but I pout on 87 octane. I have always run 93 in...

    0-60 with Trifecta tune

    Finally got a decent run. My UG does not read the 60 number in cold weather. Don't know why. 2015 sedan; 1.4T; 6M Trifecta tune installed in January. Bad 0-30 time but the 30-60 is very strong. I've seen around 2 sec for the 0-30 time but I question if that was real. I'm very happy with this...

    New Trifecta tune

    I just put the new Trifecta tune on my 15 LT 6M turbo. Some time ago I sort of complained that when folks did this sort of thing all you got was a bunch of "wow" and no numbers to back it up. I'm now going to do that exact thing I ragged about. Wow! I can run consistent 7.8 second 0-60's in my...

    A new and better Trifecta tune

    It seems like there is an updated Trifecta package that, according to what I've read, seems to eliminate those complaints about the sort of "digital", on/off operation of the tune. I like the idea of the Select Tune being triggered by the cruise control. I was leaning heavily towards BNR and...

    0-60 with Ultragauge

    First post (other than the 10 in the sticky). I have a 2015 LT with the 1.4 and the 6 manual. It has 800 miles on it and is bone stock. Put the Ultragauge on yesterday to see how some things were working. Looks like the boost gets to around 16 psig on average. 0 to 60 was 8.36 seconds in...

    Just picked up the Sonic LT turbo

    Howdy! Just picked up a Crystal Red sedan with the turbo and the 6 speed manual. Got into this from a 2006 Chevy Aveo with 161K on it. Big difference! Only has 80 miles on it but I love it. I have the 15" wheels and I'm thinking about going to 17's to fill out the wheel wells. The whole tuning...
