Ok currently i have the drag comp on my truck wire tapped everything. But i was wondering if its worth the hassle of selling the Drag Comp and buying a TST POWERMAX Ce? Drag is 140 and Tst is 150 but tst has more torque. What would yall do?

 

I would keep the drag comp and borrow someones TST Comp box and see what you think.

 

Tough question! problem is, very few have ever used/tested both boxes.
I would not bother, unless you can get your money out of the Drag Comp.

I love my TST PM3 stacked with the EZ and feel it is a heavier fueling box , but the difference is not worth spending much money, unless you have it lying around.

The TST Comp model (assume that's what you mean by Ce) is awesome, but, IMO, will not give you all it can unless you have a Hot Rod VP-44. The TST PM3 is programed to deliver ALL the stock VP-44 can deliver.... and the stock VP-44 can't deliver all the fuel the COMP model calls for... resulting in a little more power but a shutter at max settings! With the HRVP-44 I have been told the TST Comp has added 180 HP.

I'd only go to the TST if you get sick of your Comp crapping out regularly.

Most people regard the TSTce as the hardest fueling box you can get for a 24V. But it also has very bad manners, is known to shudder a lot (sometimes stalling the truck), and has a reputation as a pump eater (especially with the custom programs that push fueling to 80%)

Standard PM3 will fuel at about 60%, which is still pretty hot (way more than an HO can handle, for example).

If it's more power you seek, ditch the Drag Comp and go to a TST/Smarty Tuner stack. Initial testing of this combo is VERY impressive, with a bottom end that is simply unequalled.

I doubt that most people would consider the slight improvement in overall hp, and the good improvement down low to be worth the $$$.

Divorces are expensive, just less so with a fueling box you are married to.

 

I believe Joefarmer ran both setup's on his 600+ HP 99...if he doesn't chime in tonight, you might PM him!

Something about the PM3/EZ bucking with Mach 6 sticks at low boost!

Id say you have plenty of fuel. GET A TURBO! An HTB2 or so would be nice on that thing. Or maybe hx35/3HT3B twins? Seriously though. If i were you and wanted to spend the money; go with a nice turbo. Should get you into the 13's with a lot better EGT's.

Ok great info here....Let me throw this one out and tell me what yall think. I have a buddy with the same truck as mine but with a 42/40 turbo. And he is running a Comp in EZ mode and a TST Ce 150hp. He said he loves it cause the TST is a fueling box and the comp is a timing box. The turbo is not gonna be a problem cause im taking his turbo (42/40) and he is doing twins. 40/3b. But the only thing im worried about is killing my VP44. What do yall think?

 

I have both boxes and have tested both. RJ and Hohn are correct, not really worth it unless MAX HP is your only goal. Street manners go to the Edge Box, smooth power. The TST CE is very hard hitting, only the lower 4 settings are useful on the street. The upper settings produce violent pump shudder unless you keep your foot planted to the firewall, even then you can get shudder when you let out of it. That will destroy a pump in short order. Keeping egts in check on the higher settings will be tough, I can peg my gauge (1600) even with my setup. I do run a TST HRVP with the CE box and gained 70 rwhp over the Drag Comp. But if you use your box a lot I would keep what you have. AS Hohn said, the Edge fuels at 63% max, the TST with a custom program will override the "safe" zone (63%). This puts a huge strain on the electronics in the pump.

Doen't Mark Chappel's HVRP provide enough fuel to solve the shudder problems?

RJ

 

I've never heard of ANY hrvp solving the shudder problem with the TSTce.


I don't know how or why the shudder is there for sure, but if I had to Balderdash it, I would say the following:

The shudder is caused by the fact that the metering solenoid in the VP is fed by the internal little pump. You crank up the fueling, and the solenoid is VERY busy! Next thing you know, the plungers are draining really fast.

When you go cut the loud pedal, the solenoid slows way down before the rest of the pump, and the plungers don't get the fuel they need. Then you get cavitation or a stumble.


Anyway, that's my theory. Maybe Don, Keith, or someone like that could explain the shudder to us?

 

I'm with you on this one too. Get a turbo or are you just waiting for the stock one to explode? That stock one is WAY out of its map with all that fuel your throwing at it.

 

Unfortunately, no it doesn't. I run a very aggressive program that fuels till 3900 hard, and on level 4 and up I will get hard shudder if I give any more than 1/4 throttle and let off, actually closer to an 1/8 . The truck is super responsive though with the ecm. I never even run with the box on, no need to. I love the box though, you just learn to adapt your driving style to avoid problems.

Hohn, I believe you are correct in your thinking. That solenoid is way beyond its duty cycle in the Ce box.

I did run a standard TST box for a while, and although I never dyno'd, my SOP meter told me it was stronger than a Drag Comp. ANd it never shuddered on any level.

Fred

 

Thanks!
I tried one once (borrowed) and on my truck, I had no shudder through setting #5. Above that... it pulled very nicely, and noticable harder... as long as I stayed in it, but there was just no way to back out slowly without a double shudder..... a quick "thwap-thwap"?

Haisley told me their HRVP-44 will handle the Red Line Box with no problems. (The one they sell is actually made by Scheid) Is the TSTce even heavier fueling than the Red Line?

RJ

 

I have ran all 3 big power boxs and dynoed each of them(TST Comp, Drag Comp, and Red Line) the power between them is less than 5 on my truck. Remember if you buy a fuel only box like the TST you will need a timing box or Smarty for big power. With the TST and no timing I lost 60hp compared to a drag comp or the tst stacked w/ a ez. Tim

 

Like Chris said, I ran the PM3/EZ stack for 3 months. Got tired of the shudder (daily driver) and switched to Drag Comp(s). I toasted 3 drag comps within their 1 year warranty, but if I ever have to own a VP it will get a drag comp. Good value, single box and you don't have novice drivers killing the truck after every run. That said, each to his own.
