Gearhead.
It was between them & MPT for me (or livernois but they came out late & didn’t have trans tuning immediately) & I am VERY picky when it comes to performance mods.
In a nutshell my raptor w/ a gearhead tune drives exactly as you’d imagine a stock one w/ an extra 100hp/tq & better trans tuning would from the factory. Doesn’t feel “modified” just feels much faster/smoother & more responsive.
Their trans tuning is buttery smooth & slick shifting. I’d have a tough time believing another company puts out better/smoother tranny files.
My main goal was reliability & daily driver manners w/ more power & ability to “set it & forget it”- my understanding w/ MPT & some other s they push the boost & A/F mix close to stock limits & also require the highest octane- even a drop from 93 to 91 can cause issues on tunes like this, as can the occasional stale tank of gas or in the even of a real screwup your wife accidentally filling up w/ 87 and/or being on a road trip forgot the device running a 93prx tune & no 93 in sight - better hope you find some octane booster. Gearhead’s tunes have an octane “autoadjust” feature to compensate in case you have to run 87 or 89 etc.
how does gearhead add 100hp/tq and not push it to the stock limits?
