Engine/Transmission (1998.5 - 2002) TST, are they bull****ting?

[JdmFreak]

As the sig says i have a 02 HO. I had the TST pm3 on and after seeing some friends trucks with the same box i noticed mine wasnt performing that well. Tested all my connections and sensors... everything is fine. SO i send the box back to TST to get the comp program put on. It was something i was wanting to do anyway and i figured all that was left that could be wrong was bad software. Got the box back today and just for curiosity sake i called TST to see what kind of power that program was supposed to make. His responce... ... . 80hp added total and the comp software had no gain over the regular on the HO engines. He attributed this to the fact that that the mechanical limits of the VP on the HO would not make anymore than that. Did i screw up with Getting a HO or is he blowing smoke up my ***. If he is telling the truth what are my options on being able to flow enough fuel to support some more power.

 

[Tcolesanti]

I have heard that HO pumps put down a max of 90-95hp from a box, the rest would need to be had from injectors.

 

[Joseph Donnelly]

TST told the truth about the box mod to the pump. Now, go out and buy some injectors. The RV injectors add 42 hp on an otherwise stock HO. Diesel Dynamics can supply you with injectors good for 2 or 3 times that gain.

 

[SSabick]

I have read it on here some where on here, that a mach 6 injector, and a mach 4 injector shows no more gain in HP, but does have better pulling power hooked to a sled? Is there nothing that can be done to correct the lack of fuel?

 

[JdmFreak]

I have a set of Jammer 4s but i need the turbo to back them up. Just got the TST box in with the edge EZ. My god thats alot of smoke..... heres the thing. I have the stock clutch in and it still doesnt slip im seeing 36psi and gobs and gobs of smoke. Something has to be up. Am i able to run a non HO VP to allow it to push more fuel. Im planning on doing a TT set up with an hx40 and HT60. Already have the big guy still waiting on the little one. Just making sure im not going to run out of fuel.

 

[SpicyJam]

No you can't get away from the amount of fuel the little VP pushes out. Even if you can get a ECM to read a ETC VP, the timing the HO has will kill it. BTW 90 ponies is all they will put out, a little better than the 80 you had mentioned above.

The route I will take when my VP dies is to install a P-pump and be rid of the eltronics,but hey you can still enjoy the power made by our HO's... ... ... . lol. As far as your clutch, I destroyed mine *** soon as I would put my box on 5 x 5, I had the TST Comp box, and really disliked it. So I went bcak to EGDE. Later Jim.

 

[JdmFreak]

I guess my queston should be... . with the parts i mentioned above, am i going to be able to use the VP. trying for 500whp becuase everyone (my car buddies) says it cant be done. Am i looking at more than just a FASS to be able to support the power i desire. As much as i have searched i have never seen anyone complaining of lack of fuel, at least because of the VP.

Re: Vp44

Yes we can help you! We have a VP44 pump that we call our super high output. It adds 60 hp to 100 hp depending on injectors that you are using. We have sold thousands of these pumps with good results. There has been a alot of boxes stacked and every variation that you could think of and they always say it works great. Some of the highest hp 24 valve trucks have our pump on their engine. We also have injectors, everything from extruded to EDM injectors. Our latest release is a turbo we call a Phat Shaft 66 which has seen alot of interest. Todate there has been a lot of positive results reported to us, but that does not suprise us because we have done alot of testing to arrive at this product.

Now you have my attention, how did you get the ECM to read a ETC pump, or what have you done to the HO pump to push more fuel? Because if I was to put a ETC pump on my truck it stays in limp mode, next how did you rid the extra timing that the HO puts out. Since I am in the diesel business and have been talking about this very subject with Pier's, and Haisley's I am wondering how you guys came up with it. If you do indeed have a bigger VP that would run on a HO I would be intrested, but I would really need to see the proof. Please PM me and if you have info, such as documented HP gains on a HO. I am already close to 500 hp with my tiny VP and a change of turbo's would help out greatly, since I have yet to build my own set of twins. But if you really have a pump that adds such power I would like to know. Thanks Jim.

 

[jabird]

We all would... ... ... ...

 

[JdmFreak]

If i do upgrade pumps i will most likely not go with the VP again. I have read too many stories on how the Hot Rod VP44s have no proof that they are infact a better pump. I already have a regular VP with waranty that cant be voided, i just have to kill it once a year to get a new one. Just trying to figure out if it will flow enough fuel with inkectors and boxes to make the power i want. If you do have the proof that your pump is better, id be very interested to hear. PM me, or, post it up so we can all learn.

I believe you have to run an ETC pump, and have your ECM reflashed to Standard Output parameters, effectively giving you an ETC motor with more compression.

 

[SpicyJam]

Well would that not go along with just simply putting on a ETC ECM? If so that didn't work, that only worked with the box on 3 or higher to get the right pulse out of it, so I shouldn't say it doesn't work, I am not looking for that either. So where or who could reflash the ECM if that works?

 

[Tcolesanti]

No the injection pumps are completely different, your right, the HO pump will not communicate properly with a SO ECM. What you need is an SO pump with a SO ECM. The SO pumps are not capable of as much timing as the HO pump but it has 7. 5mm plungers, vice the 7. 0mm plungers of the HO pump, i. e. MORE FUEL.

 

[RJPotts]

Absolutely, the SO pump is the way to go if you want to make more power.

If you want to make a ridiculous amount of power the p-pump conversion is the way to go, but I've never heard of anyone doing the p-pump on anything but a race truck and being happy with it. As far as I understand driveability, reliability, cleanliness goes out the door... but I may be wrong.
