All the threads I have read, that is not a legal limit. Its not on the door sticker.

From what I read, the axle weights (GAWR) and possibly the GVWR (in some places) are your "legal" limits.

I'm not a lawyer, but that seems to be the general consensus.

 

From my 2015 book. My GCWR is the total weight truck, trailer and all gear.My book with 2015 towing specs has 19,000lbs for 3.73 and 22,000lbs for 4.30 gears. This is total truck and trailer combined. My trailer and truck currently weight 20,020lbs. Trailer by itself is 12,580lbs and truck weighed 7,440lbs.

 

The way my truck is configured it's rated to pull a 15600 trailer with a combined of 22500. Last time I weighed the trailer was 15900 with a combined of 24400. Not to worried the same truck with a 6.7 is rated to pull 22800 with a combined of 30000, the only difference is the motor.

Yea man.... Enjoy your newer new truck. FYI. The performance 87 tune is even better

 

I will swap it in next....Thanks

 

Agreed.

 

Oh, ok. Let me make this clear. MGP went down. Not drastically, but about 1.5 mpg around town, and I attribute this to my foot on the skinny pedal because it is fun, and the more power.


With regard to my "investment" and return on said investment, I am referring to drivability, performance, and fun factor- period. I did not buy and would never buy a tuner for MPG increase, no matter what I am tuning. If I can gain MPG, then sure, why not. However, I want it for "go factor" - plain and simple.


If 400 bucks can put a smile on my face every single time I get behind the wheel, then my investment was well worth it.

 

What I've read on the tuner for the 6.2 is you don't really gain power. 5hp and 7-10tq at most. What people feel is the shifts and throttle response. To me a tuner isn't worth it on a gas engine. I Would spend the 400 on a new hand gun or something else besides a tuner for a gas truck.

 

Have you checked out the dyno graphs?:



If 5star is getting between 15-25 hp on the dyno, that is more like 20-35 at the crank with just a tuning mod. I'm ok with that. The tuner allows me future mods to be done via an emailed custom tune...and most of all I know it will work on my new F250 3.5EB someday. The custom tuning does a lot on the EB, not as much on the 6.2 though.

 

trust me you won't get that much to the wheels with a tune on these trucks. We will be lucky to get 5-10. You can't just go off of dyno numbers cause people can mess with that.

 

Ok, then. We get it. Go drive an oil burner, then. I have, and I am over it. I was a 12 and 24v dodge guy for years and had rigs that ran 800hp plus on a dyno. Yes, at the wheels. They were awesome, but tentative as heck, unreliable, and devastating to the drivetrain.


For the 6.2, I am not relying on Tuner company's published numbers or anything, so I cannot attest to that. I could not care any less about some graph published about tq or hp. I take it at face value.


All I know is what works, plainly put. If I hammer the gas from a standstill, stock, it is ok. When I hammer the gas running a 5star perf tune, it rips the rear tires loose and beats the friggin' b*lls off of the stock setup. Night an day difference, literally. That's all I know. I am not connected to 5star, ford, or anything. Just speaking from experience, and I can drive it like that every day...


I have been running vehicles in everything from strip/street drags to SCCA club events for 20 years, and am pretty handy with both a computer and a wrench. I can tell you that the 5star tuning made a WORLD of difference on this 6.2 and its daily drivability, and this motor is a beast with some good tuning.

 

That's the throttle response that you feel. It's not from the amount of power you gain. The throttle body is wide open with their tune as soon as you floor it where the stock tune the throttle body is half way open. Like I said what you get with a tune is throttle response and shifting. Which to me that's not worth 400-500 dollars. I'm just posting my opinion and everyone can do what they want.

 

Call it what you want:


Throttle response I can feel? Count me in.


Better shifting and hookup? I'll take it.


400 bucks for that and no loss reliability or longevity? SIGN ME UP.


Again, it's my opinion as well, but I am just sharing how happy I am with it........


Every. Single. Time.

 

I already own an SCT from 5*. I ran Mike's tunes on my 2011EB and it was amazing. Maybe I'll try a tune for my 6.2. I would get the 87 tow like I had before.

 

You say that but have you driven one with a tune? Easily worth 400-500 dollars because you get to enjoy it "Every. Single. Time" LOL.

Of course everyone's driving style is different. It's just a matter of opinion.
