After all of the reviews of the H&S, I would expect it to burn the tires more?
I called H&S and they had me reinstall the preset tune. This did not make a difference. All in all the exhaust sounds amazing but I'm not happy with the performance of the truck. My uncle has this same tuner on his 6.4 F250 and it runs like a beast without any bogging.
Is this normal or has anyone else experienced the same issues?
Also my MPGs have actually decreased by 1-2mpgs(and I drive like a grandma without towing) since the tuner was installed.
Any feed back will be great!
Jason, I'm not an expert, but I know mine doesn't do that. Are you running an aftermarket intake? The reason I ask is because the generic tune can only please a few setups. I ran mine with a S&B intake with the lid on for about a week, I pulled the lid off and it made a significant difference. I was initially getting at least 2mpg lower until I pulled the lid off and now I'm averaging 18.7 and better throttle response. I kind of cracked the code on tuning with, believe it or not, a Harley VROD. When I say cracked the code, I mean I understood the variables in tuning. I used a PCIII tuner and you can modify several tables. So.... The smart guys could come up with a tune and share it. The great thing about that is that there were literally hundreds of custom tune files available on a forum and I could find one with the exact same brand and parts I had, download that tune and basically have a Dyno proven load. Yeah, altitude, temperature etc could also be factors, but for the most part, the tune was spot on. Hope this helps.
