It is such an amazing tune, I can chirp the tires in third gear and the drive ability is very top tier. There is no turbo lag even with an oversized stage 2 kc turbo on stock injectors. Shifts very clean and smooth and gets out of overdrive when I want to get out a lot easier. Couldn’t have asked for a better tune.
Definitely very impressed with the tunes that I received. Paid for them the evening before and by 12 noon I already had them the next day very fast service as well.
I recently did a bunch of engine work to my 6.0 Powerstroke. This is the 4th one I’ve owned since 2012. I always used another tuner previously and this one was no different. I had just gotten the engine running and I could tell something was off. I spent weeks troubleshooting and pressure testing and double checking. All the while in conversation with my tuner. I finally didn’t know what else to do but get different tunes. I reached out to Gearhead and wow. My truck was back! Runs better from idle, smoke down low is almost gone, egts are lower, boost is higher. The truck runs great. Highly recommend!
2007 F350 with studs, 175/30s, KC stage 2, modified direct drive solenoid, and a Thumper I, runs amazing, shifts are on point and power is smooth, once you mash the skinny pedal to the wood then it really wakes up and takes off. Been running Gearhead since my first diesel and still the best tuning I have ever ran, had them in my 6.4 for a decade and never an issue.
Runs great throws no egr related codes and shifts great, went from SCT x4 canned 50hp to the GH SRL tune and lord it’s big difference in low to mid range and pulls longer on the topend, running on stock head bolts turbo injectors just blue spring kit and I’ve enjoyed the tune for 2 weeks, so far it’s good and rolls a little coal! Highly recommend this and so much better than canned tunes! Thanks GH!
First 6.0 diesel I have owned and have gear heads on sct x4 truck is something else I have had it tuned for 3 months know and the truck performance fantastic. With the tunes the truck will get down with the get down. Performs well and sounds great with the tunes
I Love my GH Tunes! So much so, I renamed 1 of them in my system to HeartBreaker😬 Cause that’s exactly what it’ll do for the Sports Car Guys💁🏻♂️
Very good tunes
Transmission shifted extremely hard and during full throttle feel as it was defueling to heavily causing power loss.
Great tune package all around for my 6.0 running them on stock and have noticed far more power like it’s woken up and better shifting as well as better fuel economy 10/10
Just what I was looking for, awesome tunes runs and shifts like a beast to be mostly stock. Thanks
Be sure to ask and pay for the overdrive - tow haul lock out !
Amazing tunes, love how they shift and lock up the torque converter, tons of power and torque, clean running no smoke, improved my mpg around town by 2mpg
Tunes run great, I have a lot of modifications to my truck and i have some to learn about any adjustments that others like to tweak. But with all the extensive work I've done to my truck have my f350 dually flaunt its fat ass and fade away ahead in the distance to most any urban bro in his $80K car his dad bought him, while still having the capacity to tow gooseneck at full capacity. These tunes deliver that punch to do it, keeping my EGTs in check when towing and the fuel flowing when I wanna play.
IN ALL seriousness though, They run much better the the Blessed performance tunes I had uploaded previously to my Livewire, and on top I forgot to inform them i had an upgraded 100PSI MAP sensor i needed to install when I originally paid for the tunes and gave them all the details on my truck until I contacted them a month after the original tune delivery. They took care of me responding right away and not charging me any extra gees to update the files even though it was well past the given timframe to do so. They sent the updated file promptly and didnt drag me around putting me off. Ill be ordering tunes for my 7.3L Powerstroke soon as well when I get it running properly so I will/would definitely buy again
I am very satisfied with choosing gearhead tuning for my 05 f250 6.0. Its a a completely different truck compared to the canned sct tunes (night and day difference). I would definitely recommend gearhead to anyone driving a 6.0.
Truck runs so much better power comes on great very happy with the tunes and fuel mileage is surprisingly much better
Had a issue and they helped diagnosed the issue with being a bad IPR sensor. Tunes work great now !
Love the way my Excursion runs with a Kc stage 2 and 190cc/30% with GH tuning !
Have also requested tow / haul OD kick out
Some of the best tuning you'll ever run. There are lots of great 6.0 tuners out there, but Gearhead has consistently been exceptional in multiple areas. The tuning runs great, loads of power, shifting is beautiful, and nearly zero emissions. The customer service after the sale is just as excellent. Questions? A quick email gets your answers. Need revisions? Easy and painless. You cannot go wrong with Gearhead 6.0 tuning. Get the SRL tune, and thank me later.
They are amazing
Tunes are great. Low smoke and low egts
Went up and beyond to help me get the truck straight with the tunes and very knowledgeable
I have the Tow unlimited, 8K Tow and SRL and compared to the other tuners on the market its not even close. Best response, best shifting and quickest spool. Would highly recommend
