    Methanol Injection and Gearhead Tuning Purely Technical

    Let's keep it technical this time..... The AO file uses the average knock sensor activity to swing a parameter knows as OAR (octane adjust ratio). It is used heavily on the 15+ trucks but was never utilized the way I use it on the SHO. The parameter selects from 3 boost maps and the way I set...

    How Do I Drain GH Intercooler?

    Hey everyone, My car's approaching about 68k miles, and I've been wanting to drain the Gearhead intercooler for a while. The IC was put on by the prior owner, and in total probably has been on the car for four years. I've been suspecting some pre-ignition lately, and seeing as I don't see an...

    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...

    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. Seeing as it was both banks simultaneously, and right when it's warming up and lowering ethanol levels, and I'm at...

    High LTFT Both Banks Idle/Under Load

    Hey everyone, Came back from a week and a half away staying with my grandpa during hospice, and had left my car in a temperature controlled garage. Started up sounding a bit colder than expected, and down the road a bit after a pull, received a blinking CEL for a short period before it...

    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...

    Winter project...

    Snap shot story.. Ford replaced my engine with a Ford reman, 30k miles in it lifted the head due to not cleaning one of the head bolt locations in the block. While apart I ported the heads and had them drop in ARP studs. 8K later and out of warranty it eats a couple rod bearings. I drop a...

    Best Tuner Recommendations

    Hello guys! I’m simply asking for comments/recommendations on different tuners! I currently have a 2013 PP SHO, Livernois sucked with it so I switched to GearHead and that seems a bit better and “smoother” shifting-wise. I’m now selling my 2013 to grab a new model (2017+). Just wondering if...

    GH versus Livernois

    Hey guys. Awhile back I had posted about my Livernois tune, which I had updated with a stock-shifting tune which DID indeed help the shifting quite a bit. With that said, 1st gear is solid every time, but 2nd gear in WOT it shutters, just doesn’t feel good on the tranny (which only has 20k miles...

    GH Tune ... baby steps

    Am working my way into a GH tune. My first mod. So far, I just have the bits and pieces. I am very very happy with the responsiveness of GearHead, very. I am troubled by how the SCT BDX works -- it's very wobbly and I didn't have a great start with this thing. It kept throwing errors, and while...
