    Getting to the Bottom of Dropping OAR

    Hey all, I'm trying to put a pin in the reason my OAR has dropped a bit lately. I'm on Gearhead's e30 Tune, at about 67k miles now (specs in sig), and for a while through this winter I was running at a very happy -0.99 OAR on roughly e35-e40. I know some positive KR is expected to counteract...

    2017 SHO for trade.

    This is a far fetched idea but I’m needing a pickup truck. I’m not really brand loyal so I’m just taking the chance to see if anyone is interested. This car never ever gets driven and just sits. It’s a 2017 with 80k miles. Has catless downpipes w/ defoulers so it passes emissions no problem...

    Cat Codes and Tough O2 Sensor

    Recently, I reduced my E content I was using on my GH AO 93 tune to cover for bad winter gas, down to 15-19, and I received a CEL for 0420 and 0430, cat efficiency below threshold.

    Knock Sensor Acting Up

    Hey everyone, I own a 2018 58k mile SHO with the gearhead AO tune, intercooler and HPFP, as well as a few other common mods running 93 Octane, that I actually purchased from another member of these forums. Today I was driving in very cold temps (10 degrees Fahrenheit) when I noticed that on...

    Sport Mode shifting

    Hey. I run GH tune and have just now noticing the shifting is different between sport mode and drive. With this said, I have gotten numerous tune revisions. One quick question. 1. Is there a way to get sport mode to go into 6th gear? I just had a tune that I used for a couple months and when I...

    Engine mounts

    Hello! I have GH tune for my 2013 PP SHO and after revising it several times, it did get better but it’s not fully perfect. I do understand the shifts will be more firm, and although my shifts are firm I still feel like there is room for improvement. I can’t quite out into words what it feels...
