First Impressions TST Box.

[BillGotthelf]

No smoke that I can see on lower levels-start to see some at level 5-6 and heavier on 8-9. Not anywhere near the smoke my 99 puts out-it will black out the S. Fla sun. Well some of that smoke could have been my HO clutch. Its history and I am trying out the new LUK Pro Gold Series. Mark at TST is trying this one out too. If it holds the power and tows good it will save some $$ over others.

I just wanted to jump in and give my . 2 cents of the PMCR. I would like to start by saying hats off to TST for this awesome box. From what everyone is saying 5/5 and 6/6 are holding with the 5 and 6 spd transmission's. My clutch will not hold 4/4 without slipping so I don't have a lot of info to give at this time. I was able to drive around on 7hp & 2tq for awhile today without the clutch slipping. The highest I seen the EGT's was mid 1,400's +or- . There was a little bit of hesitation in the higher rpm's from lack of fuel. I am going to install the South Bend Street Twin clutch this coming week, which should hold without a doubt. I will post more info as soon as I can.

My TST box will be on the way soon and I will be experimenting like everyone else. Is it my understanding the box is strong enough to cause the clutch to slip on an unloaded 6-speed?



And if so, which gear slips the most?

I'm still in question on my liking to the TST box. I have been running one for a couple of days now and after I replaced the 3amp fuses, it make good power, but it isn't consistent. When in high power and torque settings, the truck totally changes sounds when accelerating hard. After I let off of the accel pedal, the engine will lunge or knock a couple of times while slowing down. I will call TST tommorrow and see if this is normal or what, but if it is, I'm not real pleased with it compared to the peaceful power of my Edge.

Lonestar,



What levels do you have it set on when it does what you describe? Do you have an auto or 6spd?

Not real pleased w/TST?

DO keep us posted!

The box does this on the higher settings like 5/5 and up. Don't get me wrong, the box produced TREMENDOUS power, but just doesn't feel right to me.



I will hopefully talk with TST today and get some more information. When the sound of the exhaust changes, it is almost like the truck is wanting to go, but just isn't getting the fuel at the right time to get a good burn. The egt's also get extreme when this is prevelant.



I don't know if the timing isn't correct for my application or what, but I am curious to know if anyone else is having similar symptoms.



I have an 03' with the 47re upgraded by BD with their LX torque converter, Valve Body, and their pressure loc kit. I am also running Diesel Dynamics stage 3 injectors, and their pusher pump and fuel line kit. My next move after getting the PowerMaxCR worked out will be a set of twins

OK dumb question. I have seen a couple of these posts where people are so happy that EGT are in the 1400-1500 area. What ever happen to the fact that Cummins says not over 1250



Or do people just not care about melting pistons. Personaly I never let mine get above 1200 (I think my EGT is off by 50-75). Actually I have a hard time even getting above 1200. Guess I want mine to last along time and seeing people hitting 1400 make me worry.

Looking at what you wrote i am maybe thinking its because of you injectors along with the box. I dont think ive seen anyone running that combo yet... Just a thought. . keep us updated

I'm thinking the same thing. I wouldn't be surprised if the injectors and high TST settings have done maxed the ol' CP3 out. It's a sickening thought and I'm wondering how high I'll be able to go with my DDIIs.

 

[XcumminsX]

Well thats not a bad thing... Now someone will have to make it work... And then MORE power for all



I am just sitting back waiting on all of this... Id like to run DDIII's with a tst box and im not sure what turbo now. I know the KSb1 can hold good egts, with the box so who knows what will work... Just sittin back enjoying the show... And when the show is over... 550 + hp from me

x,



the limitation on these trucks have been they are running out of fuel. we need a bigger rail or somthing i dont know. x i would recomend twins so you can run it all day long. i see you dad owns a machine shop just get some help from somone at work use you hy35 as your 1st turbine and then get a stock ht3b wastegate it b/t the two exhast housings and there you go. bullydog has already done this. but if you want 550hp and manageable egt start planning on going this route. or maybe you wont have to with a ksb1. but by the time you pay for that ksb1 you could have twins and be running cooler egt's. i dont think i will give you any other advantage other than egts but what do i know. just a thought.

Mopar Mudder you are correct, 1200 is where your danger point begins. I have run trucks in the 1400+ range for years and never had one melt yet. There is a big difference from hitting 1400 and holding it at 1400. I have been told that cummins run's a 5 minute test at 1500 on a dyno and it held together. Now this may be true I don't know but it came from a reliable source. I'm sure there are some guys on this thread can give higher EGT's #'s than what I have seen. Max egt's seen to date on my own truck 1600 01 powerstroke. Also keep in mind if your post turbo on your probe you are more than likely close to 1400. Now I'm not saying to run your trucks EGT past 1200 all the time, just with my experience I have not had a problem going past 1400 (YET). I hope this gives you the information you where looking for.

Yea my probe is pre turbo. Which bring another point.



It has been reported that the back cylinder runs hotter then the rest, I don't know this for sure. But I think most are measuring off the front of the manifold split like me. So even though the guages says 1200 you could have a cylinder at 1300 or higher.



I here what you are saying about short bursts, I like to play it on the safe side of thing.



I wouldn't doubt that you could run 5 mins at 1500, but what kind of damage was done and what did it do the the life of the engine.



I just wanted to make sure that some one didn't go melt down their new motor cause they saw someone on TDR was running 1400 so it must be OK, you know how things can get misinterpreted some times.

I'm pretty sure you'd be well past the CP3 by this point and will always have stumbling and drivability problems, even with a good pusher pump setup like DD's.

OK... . now for the ALL TIME DUMB QUESTION... Is the Edge or TST boxes good for making power for towing? The reason I ask this is the 5. 2L gasser I had, the "chip" was not recomended for towing. It only gave you more go... .

 

[wxman]

Where are you guys with the TST PMCR and 6 speed mounting your in-cab controller/monitor?

 

[XcumminsX]

PUG. . The tst is the newer chip that does timing and duration. . You can tow with the chip... Not anything like gassers

I was kind of afraid of that scenario myself. Do you think the CP3 is just pumping all it can or am I not getting the fuel from the tank to the pump. I am running DD pusher pump and fuel line kit, which I thought would help, so I'm kinda lost here. I didn't get the chance to speak with TST today, so I don't know anything yet.



Another issue I am having is the "knock" noise that I hear when I let off of the fuel. The engine makes 3 or 4 "knocks" with a like surge of the engine. I guess I'll have a stumper for Mark

Pug-I'll be towing with mine this weekend I'll let you know. I plan on towing at level 3/3 and with the new clutch/pressure plate (Luk Pro Gold) it should be okay. I'll keep an eye on the egt's.

Wxman-I mounted mine on the steering column between the speedo and tach. If you use the velcro that comes with the kit and mount it right back against the plastic trim around the instrument cluster it does not block the view of anything and you can oute the wire down between the column and dash.
