I have been a "lurker" on this website for a few years now ever since I had my old 2002 1500 4X4 but never post. I now have a 2010 Hemi and am thinking about getting a tuner, hence this post.

I am confused on the HP and TQ gains you get from the Superchips.


The Superchips own website for the 3865:

https://www.superchips.com/Store/tab...q/Default.aspx

This clearly states the max gains are:

91 Oct - 17.8 hp @ 3500 rpm and 26.3 tq @ 3550 rpm
(It also says that a Dyno Sheet is not available)


Superchips own website Forum states from a post (2nd one down) from "RON@SUPERCHIPS":

http://www.superchips.com/forum/view...mi+power+gains

Now this states the max gains are:

93 Perf Maximum Load (OEM or # lbs) Not for towing
Max HP Gain @ RPM 25 HP @ RPM 5700
Max TQ Gain @ RPM 30 TQ @ RPM 4000

91 Performance Rec. Fuel: Min. 91 Octane
Maximum Load (OEM or # lbs) Not for towing
Max HP Gain @ RPM 20 HP @ RPM 5700
Max TQ Gain @ RPM 28 TQ @ RPM 4000

Tow Rec. Fuel: Min. 91 Octane
Maximum Load (OEM or # lbs)
Max HP Gain @ RPM 20 HP @ RPM 5700
Max TQ Gain @ RPM 28 TQ @ RPM 4000


Then there is yet another post made by "RON@SUPERCHIPS" on the Superchips Forum where he posts this And then when questioned by another poster in that Thread about how his numbers are almost double what Superchips claim everywhere else, he replies with this

Here is the Dyno graph that he posted supporting his numbers:




A Forum member here named "SilsHemi" replied to another member named "Ironhayden" who questioned him about all the different numbers given by Superchips:

I am assuming that SisHemi works at Superchips in order for him to know this ?




I am just really confused about all these different gain numbers.

SilsHemi here says that Superchips simply didn't update their website with he 40 HP numbers yet................... well he made that post 3/29/2011, it's almost 4/29/12 and Superchips still has 17.8 HP & 26.3 TQ listed on its website......why would they not update their website after more than a year to show even better performance numbers ?

RON@SUPERCHIPS on their own Forum website has replied to posts asking for Dyno sheet results for the Hemi on all the different tunes you can get, and he always says that he doesn't have any other than the one he posted (see above) for the 91 Octane tune........... as if all the different numbers gain isn't confusing enough, why would they not have any dynos of the other tunes, and only have the 91 octane one ?


Has anyone here actually dynoed their stock Gen 4 Hemi with only the 3865 ?

 

See, i could care less about the difference in numbers. i could care less if it even made any additonal HP/TQ.
The Advance transmission tune and MDS disable for the 2004-2010 is worth what the tuner provides. As long as I have those 2 things, I'm good. I could care less about a dyno sheet. Your butt can't tell 10hp anyways, 30 maybe, but not 10. 10hp will only gain you 1mph in the 1/4mi trap speed. thats it.
The higher numbers could have been with supporting mods, not necessarily on a stock truck. numbers vary between any vehicle even if they are identical.

SilsHemi was a Beta tester for the whole trans tuning and as far as i know he doesn't work at Superchips which i believe is located in Florida? He is not.

 

dirtydog, thanks for replying.


I am not new to modding (just new to modding the Hemi), and agree 100% that a 10 HP gain is a Butt Dyno fantasy and that even with identical mods you can have two different dyno results, but that 40.4 HP & 37.93 TQ gain that RON@SUPERCHIPS posted about and provided the dyno graph for was supposedly for a stock 4th Gen Hemi.

Taking into account a rough guesstimate of around 18 to 20% for parasitic loss from the crank to the wheels, then according to him and SilsHemi here, that means that by just adding this Flashpaq to an otherwise stock 4th gen Hemi you will go from 390 HP to about 440 HP at the crank (if my math is even remotely close to being right............ I will be the first to admit that I suck at math though) now that I will argue you can feel on the Butt Dyno.

I just find it hard to believe that the PCM/ECU (whatever you prefer) has 50 HP to be freed up in a canned tune used for several different types of vehicles other than the Ram and before I drop $300+ on anything, I want to be sure whatever it claims to do is legit and that's why I wanted to know if anybody has dynoed the Superchips on a stock 4th Gen Hemi.

 

I don't know the numbers but I will say that the 91 tune makes a difference. Every time I have to remove it for a service trip to the dealer I am disappointed by the resulting stock power and can't wait for the tune again. I'm happy with it.

Drivetrain loss in the Rams topps the auto charts at 25%!
It's disgustingly true.
03-08's consitently dyno between 250-260rwhp.
That would put the 09+ Hemis at about 295rwhp

I wouldnt expect 50hp on hardly any gas tunes, although Dodge de-tuned the 5.9L years ago because it had a flaw in the intake system and de-tuning it was the easiest and cheapest solution for them.
With that said i wouldnt put much stock into what ANY manufacturer claims for performance increase. I bought the Superchips SOLEY for MDS and trans tuning. that's it. I use the 91oct tune with 93oct gas in the tank. Provides descent realistic gains. Again, the gains in HP were just a bonus,

The tuner is well worth $300. Like I said, spend the extra $40 for the advanced trans tune and you'll be in Heaven and feel like your driving a completely different machine. I'll NEVER go back to factory transmission slushbox shifting..ever. I'd sell it before going back to stock.


Check out the Superchips link in my sig. I compiled all Superchips infor and made a thread in the FAQ section. LOTS of INFO!!!

 

I run the 87 tune with all torque management part and full throttle set at 0%. Also have a 180 stat, Vararam intake and electric fan(no clutch fan)

Noticeable more power quicker off the line and 23+ mpg. 2WD 3.55

 

I can't vouch for a 4th Gen and my own truck has been at the dyno but with a LOT of mods, so I can't use it for comparison purposes. I have personally seen two trucks run on a dyno at stock and again after an SC performance tune though.

One was a 2001 Magnum 360 that gained damn near 50 HP and 50 TQ, which I thought was amazing for a gasser until I learned about the infamous Chrysler "Death Tune" put on these trucks at the factory.

The other was an '05 RC 4x2 Hemi and the gains were not nearly as impressive as on the 360 engine, but respectable. HP was just under 20 and TQ was just over 25...

 

I'll check out that thread, but I wanted to ask a quick question... Does the advance transmission tune offer a pre-packaged tune (like the 91 or 93 octane tunes) for the transmission settings? Or do you have to do it entirely from scratch? I'd easily spend the $40 if it was just download, tune, done, but I don't want to have to do trial & error to find out what works.

Thanks,
Rob

 

Rob, from all the info I have been trying to soak in about the SC, I am pretty sure that YES the Advance Transmission tune does offer pre-packaged settings. From what I read, you can either select the proprietary Superchips settings or select the User settings but just don't change any of the default parameters.


Cmerritt84 and HammerZ71, thanks for your input.

Rich, thanks again for replying and pointing out that link in your Sig, lots of good info in that Thread you made.......... after reading through it I felt like I even knew enough to answer Rob's question. lol

I am looking to take advantage of that $25 Superchips rebate, so looks like I have until the end of May to decide. I am thinking I will also pony up the extra $40 for the Advance Trans tune as well if I wind up getting it.

I just have to decide if the potential of running into any future warranty issues with the local Dodge dealer near me would be worth it.

Thanks again for all your replies and info.

 

There are some posts here from 2010 timeframe with shift schedules. I used carguyohios schedule as a base, not too aggressive for a daily driver. SC does not give you a sample, the default is the sc settings which is the same as without the additional trans tuning option.
