Does anyone think that the Bully Dog shift kit alone is enough to hold the Hot OJ? I have talked to several different people about this and was asked by a customer so I wanted more input. I know that they say you can run at least another 50HP on top of stock so I am just curious what everyone thinks. Thanks... Edited by: GMC2500HD

I think we are all waiting for some brave soul to try it and tell us about it. You first. http://www.dieselplace.com/forum/smileys/Evil Smile.gif

Do what i do before i sell something to a customer. Put the kit in and flog it in your truck. If you are happy, praise the hell out of it and sell it to your customers. Unfortunately i am running a 90% failure ratio on a lot of junk. Your customers will love you for it, your Allison might hate you.

Well I am looking at long term running here. I know that the Bully Dog kit is a small upgrade and I don't want to go overboard right now with my truck. Still has under 10K miles on it. I just want to have the ability at a later time to unleash the power of the Hot OJ. Was just curious and have someone else asking about it as well. He wants to do the same thing as money is the object right now. http://www.dieselplace.com/forum/smileys/Ermm.gif

My opinion on the Bullydog kit is that yes, it is probably slightly better than stock. People will push the envelope because it is a natural thing to do and do more damage than they would have if they didn;t have this false hope. I am not preaching, i am a hotrodder, i do things and believe people just like you guys. I have screwed up on product decisions and now i test on my own truck before i endorse.

Ask MBRP how it is. He has it in his 04 dually. I flogged his truck Tuesday on the dyno............i'll let him give his thoughts on it http://www.dieselplace.com/forum/smileys/Embarrased.gif

I want to know so I don't break my truck. :)

I do have this installed. It dose definatly firm up each shift, I really do like the better shifting. As for holding more power. I would bet that it does hold the extra 50 HP Bully Dog states, it will not allow you to flog the truck with a Quad 135 maxed. I think it does what it is advertisedto do............. a little extra holding power

If it doesn't improve the torque converter, I'd save my money.


Dyno testing on load cell shows the TCC lets go around 2050RPM and 725-750TQ. The Juice will adapt and reduce the power, but then you ar pretty close to the 90 HP level...

Well said.

I have two friends that both installed the Bullydog shift kit you're talking about. One truck was a 2004 Crew Cab Short Box. He's running the Bullydog 155hp program. It never zinged in 5th before the install or after. The other guy has a 2002 Extended Cab Short Box also running the Bullydog 155hp program. It has always zinged the tranny before the upgrade. After the shift kit install, it STILL does it. Every time. So, needless to say, he's back down to the 95hp program. Just some examples.

very well said, we verified what Kennedy said on a blue c/chttp://www.dieselplace.com/forum/smileys/Cry.gif

That goes back to what Mike l has said. Once you hurt your tranny, there is no substitue for new parts. It sounds like a non abused tranny could benifit from a kit like this.


I would be very interesed to here about shift quality? Usually little inexpensive kits come at the price of overly firm or even harsh shifts?


How does this thing shift? Light throttle and heavy throttle?

Light throttle is some what sharp. full throttle is just firm.


MB

Lets keep in mind this is a low $$$ part, it does not offer to fix all your performance problems for under $100. It does firm up the shifts.


I am now looking to build a trans for one of the DMAX's, with the price tag that comes with a tranny and convert, it is not for everyone. I think the shift lit deal is for those who do not ever plan on building a full tranny.

I've got a web update in the works outlining a few notes and thoughts. Should be up soon.

Kennedy,


Although I do not take everythng on your website as gospel, I do enjoy reading your comments. When are you going to give your opinion/description on the rest of the power modules/downloaders?

Well I emailed Bully Dog just for the info that they might have and this is what I got from them.


"The transgo kit does no more than that of the shift kit so ya it will hold up. Thanks"


So I am going to assume that to be a yes maybe sorta ok. Edited by: GMC2500HD

What kind of answer is that? Sounds like you bothered the head tech guy while he was skinning a racoon. http://www.dieselplace.com/forum/smileys/HiHi.gif

I have no idea what answer that is, other than he is saying that it will work for that application. That was all that I could get from that answer based on what I emailed him to ask in the first place. So I am going to try this and see what it will do and then go from there.

I dont even think that the trim valves they use have as much "thinking" in them as the Transgo kit. Once you really understand how the kit works, (thanks Mr. Cole ) you understand why each part of the kit is what it is. I do agree that its a good starting point.... buthttp://www.dieselplace.com/forum/smileys/Ermm.gif


That transgo kit shure is alot of wurk to put in seamin it dus the same thing as this hear Bulla Dog kithttp://www.dieselplace.com/forum/smileys/Confused.gif

The dyno plots are here:

Linked from paragraph here:


http://www.kennedydiesel.com/categoryresults.cfm?Category=4

So Kennedy I assume from your other testing these dips would not be there with a better TQ converter?

that is correct. Those charts are from my personal truck

GM has some funky naming of the speed sensors, but siffice to say that during the "C" test at the height of slippage, the RPM was 2156 and the input was 2041.

So let me try to some this up??? Any thing over 90 HP will possibly slip the clutches. A bully dog shift kit or better yet a transgo will allow approx 130-150 HP however you are then possibly going to slip the Torque Converter at anything over 90 HP.


So basically a stock tranny needs a shift kit and torque converter to handle anything over 90 HP on a regular basis with no slippage.


The only question I have is in regards tp the test truck. Had it ever been stacked? Had it ever been limped prior to testing?

From what I have read here, it looks like that if it slips without this $100 addon it still slips after. That tells me that it is a waste of time and money, not that the trans must be damaged. That is just a cop out to say the transmission must be damaged other wise this kit would help.


I have yet to read where the tranny slipped without it, and the kit helped enough that it no longer slips.


If it slipped before it still slips, if it didn`t slip before, it still does not slip. Everyone see where this is going?


The kit does not seem to help on slipping. Just because it shifts different, doesn`t make it better.


I have read that the Bully Dog kit will hold 50 hp above stock. I have tested my transmission to well over that before it showed signs of slip.http://www.dieselplace.com/forum/smileys/Big Smile.gif

OK


So nobody wants to give me 10 bucks for the secret.http://www.dieselplace.com/forum/smileys/Cry.gif If you remove the two trim valves and grind a flat on each valve (hand grinder is fine, it's not picky) you will have control mainline pressure dumping all over the place. You will have firm shifts (remember what I told you about firm shifts?) You will have a little more holding power on the clutches and you might get some clutches getting active when they should be asleep. Now you how to do it for free. Take the 90 bucks and treat your wife.http://www.dieselplace.com/forum/smileys/Big Smile.gif Don't forget to fix your trans either.
