Got my TST box today and some dyno runs

[SMR1TL]

Got my new chip today and got some dyno numbers for it



My truck is an 03 2500 2WD HO 6-speed. All runs were done in 5th.



My only bombs other that the box are a custom intake/filter setup (about the same as the AFE kit but cheaper) and 5" exhaust.



the 001. drf run is with the box set to 0x0. 002. drf is setting 1x1 and so on up to 008. drf which is 7x7. on run . 007. drf (setting 6x6) the clutch began to slip so the numbers don't go up much more on torque. Run 008. drf is on setting 7x7 which the clutch was acting up real bad... didn't do any runs higher than that.



Highest EGT I saw on the dyno was 1400 pre turbo on setting 7x7. On the street it will almost hit 1350 on 5x5 from stop to 100mph.



Settings 4x4 and above smoke with settings 6 & 7 completely blacking out what ever is behind you



I left the stock boost elbow in since I can hit 37psi on setting 6x6 with it... no need for the TST one unless you want to run the risk of the turbo blowing up IMHO.



No codes, no knocking and no problems. I did notice the power dip in the 2100 rpms area tough. Build number on my box is 1383.



Heres the break down on the runs:



setting-numbers--------gain-----------gain above stock



0x0 = 272hp 491tq

1x1 = 293hp 546tq +21hp +55tq

2x2 = 304hp 609tq +11hp +63tq +32hp +118tq

3x3 = 325hp 648tq +21hp +39tq +53hp +157tq

4x4 = 365hp 699tq +40hp +51tq +93hp +208tq

5x5 = 406hp 750tq +41hp +51tq +134hp +259tq

6x6 = 437hp 789tq +31hp +39tq +165hp +298tq

7x7 = 451hp 778tq +14hp ------ +179hp ------- (bad slipping clutch)

This is about the best info I have seen so far on the tst

Nice numbers by the way

 

[RAMINSPEED]

Thank you It's about time someone did this.

 

[SMR1TL]

I forgot to add that I dynoed my truck about 6 months ago with an EDGE ez on lvl 4. It put down 328hp and 607tq with the EZ and the same intake and exhaust.



Glad you guys like the info... I figured it would answer a bunch of questions for future TST owners.

isn't the install of this box tricky?

I don't think it was too bad. the toughest part was the cam sensor and those annoying little clips on the crank/cam connectors. It took me about 20 mins total taking my time and following the instructions. I already had the EGT probe installed so I didn't have to go through all of that.

 

[Gary - K7GLD]

Seems the HP comes easy, but the torque lags a bit?



Nice numbers tho' - and where are the guys who said dyno runs always are, or should be run in overdrive?

I have no idea where/what my crank cam sensors are or are located. Do the instructions paint a clear picture? Do you have to cut wires?

 

[SRadke]

The instructions are very good and include pictures. No cutting required, just unplug the sensors, plug the box harness into the sensor and and the other plug on the harness into the vehicle plug. I did mine in 20 minutes with the pyro probe pre installed.

Good numbers!!

I'm guessing that you're comparing to your 311 hp & 725tq? On 3/3 he made 325/648, but the TQ setting is only on 3... . I'm sure on level 3/9 the TQ reading would have been MUCH higher.

 

[LightmanE300]

At what setting did that one guy blow his stock turbo with this box?

 

[Gary - K7GLD]

"I'm guessing that you're comparing to your 311 hp & 725tq? On 3/3 he made 325/648, but the TQ setting is only on 3... . I'm sure on level 3/9 the TQ reading would have been MUCH higher. "



WELL, to begin with, his are still very good number - but yes, I *was* using my numbers, and similar numbers from 2nd generation trucks as a comparison - sure, at a higher setting, he DID get higher Tq - but was then at nearly 450 HP to equal the Tq *I* registered at 311 HP - see what I am getting at? Going further, if I ran MY HP up to 450, I would likely be somewhere in the neighborhood of 900-1000 ft lbs Tq...



Again, this is NOT knocking or minimizing his results, only curious at the apparent differing Tq/HP characteristics of the 2nd vs 3rd generation engines with boxes installed...



OR, are you saying with the TST box it is possible to adjust for HP or torque totally independent from each other, with NO interaction?

You can adjust HP & TQ independently. You can have 2 hp and 9 tq or 9 hp and 2 tq... or any mix and match combo you want. For whatever reason most of the guys with the TST box seem to increase the hp & tq settings in unison (3/3, 4/4, etc), but you can ramp up the low end tq on a low hp setting if you wanted. As for the max numbers, my 01 made 455/863 on a dynojet at one time. Had his clutch not been slipping MBroussard's numbers would have been right inline with that.

 

[Gary - K7GLD]

You're missing or evading my point - if, say, a guy with TST box was making 300 HP and 650 TQ on 1x1, COULD he adjust what you call the torque setting to keep HP at 300, but increase ONLY the torque to 800?



I'm betting that ANYTIME you ramp up ONE element, the other follows at a significant degree!

 

[banshee]

I'm not evading Gary. The Tq setting is more or less a low rpm fueling setting, and the hp setting is more or less the high rpm fueling.



TST does not have dyno charts of various settings for the CR box on their site, but they do have a chart showing exactly this for the Duramax box that works exactly like the CR box. You can see it on this page:



http://www.tstproducts.com/duramaxpage.htm



It just so happens that they break it down on hp level 3 for Tq settings 0, 5, and 9. You can clearly see the difference in tq while still maintaining almost exactly the same peak HP.



Is this what you're looking for??

 

[Gary - K7GLD]

WELL, UMMMmm - that's a real nifty dyno chart and all, but it's for a DURAMAX engine, and THIS is a Cummins thread...



(YES, the 2 engine types really DO behave differently!)

 

[JWine]

Whats your intake/filter setup exactly? Inquiring mind want to know.

 

[banshee]

Gary,



The fuel systems on the 2 engines are almost identical, and the two boxes work in exactly the same fashion. Beleive what you want though... .

 

[Gary - K7GLD]

Lots more to an engine's ability to generate power than a fuel system - such as long vs short stroke, low RPM vs high RPM power - if that difference didn't exist and manifest itself in different fashion for the 2 engine types, we might as well all be driving V8 diesels...



I *would* be interested in seeing that same chart for the Cummins tho...

 

[banshee]

Gary,



If the same box maker (TST) makes 2 boxes for different engines with the same fuel systems wouldn't you think they would operate in the same fashion? Obviously the numbers (power and torque) and the associated curves are going to be different, but the additional fueling occurs in exactly the same manner. You don't have to believe me if you want... call Mark Chapple at TST... he'll tell you himself.
