Bullydog on a F250 6.2 Gas V8

OK guys,
Here is my question is there anyone out there with a f250 gas that is using a Bullydog turner, air filter, and exhaust system. We are in FL and am planing to buy all this after the New Year. We have a 27 RET 5er and don't seem to have many problems on flat land execpt it dropping in and out of overdrive even when we go up and down the Interstate. So I am looking for any information???

from what ive seen on others tuned 6.2's , your gonna have that issue regardless, due to the 6spd tranny and the powerband of the motor......


that 6spd is perfect for the diesel torque and a 3.55+ rear...


the 6.2 (tuned or not) likes the higher rpm 5th offers while towing and has a tendancy to search out that range under load....


my tuned 6.7 hardly comes outta overdrive unless its a significant grade....but the torque @ 1800rpm is worlds apart from the 6.2....


either way, I like em tuned (intelligently tuned)...cant wait to delete all the junk off mine if I don't sell it.....

Guessing you have 3.73's. Switching to 4.30 would eliminate the tranny hunting. Spendy though unless you have 2wd.

If you were going to use a tuner, my suggestion would be to go with an SCT tuner instead of the bullydog.

I did the exact same mods but with a Nissan Titan. Never did notice a difference. IMO I would not buy any of it. I think you will be disappointed when it comes to pulling your camper and with an intake and exhaust you will have a lot more noise especially at higher RPMs. A custom tune would be better but I still don't think it's gonna make a huge difference. These newer gas engines have to be at higher RPMs to make their power. I now have a tundra with 5.7 and between 3-4000 RPMs it pulls amazing.

5-Star tuning seems to have good results.

Got a 2011-2015 6.2L V8 Super Duty ? - 5 Star Tuning

I like my trucks tuned as well but I I have my tuner use HP Tuners for a real dyno tune. The handhelds are ok. I believe that a tuner can tune your truck on the dyno and load up those on an SCT handheld.

Throwing your money away. Read the fine print for the exhaust and intake. It says; "UP TO xxx H.P. gain" If it was that easy to gain power and mileage wouldn't you think the factory would do this?

What ever you use be careful a tuner can void any warranty or extended warranty (don't ask me how I found this out).

Nope. The manufacturer always leaves plenty of the table so you the consumer can beat the hell out if it and still maintain warranty compliant. They also tune it hotter for emissions purposes which is not performance oriented.

I just tuned my 2004 GMC Sierra 2500 and got another 26 bhp, better throttle response and 2 more mpg. Of course this was a true tune with HP tuners and not a box tune. It is a fact that GM tuned the older LQ4 6.0s with a lot of torque management and a flat timing curve and lazy fuel enrichment.
