Stock 555, Juice or TST?

[ECappleman]

Looking for a tow and a great street driver for a stock 305/555.

I am happy with 100hp max on top, but looking for something that has better low end power (250 torque or more?) with reasonable EGTs. I would like it to start coming on somewhere between 1500- 2000 rpm.

Smoke is not a problem. :-laf



Oh. . and I have full analog gauges.



Thanks.

Either one will do what you want and price is similar. The new TST adds the benifit of the cooldown timer and overboost defueling versus the better looking package of the Edge. At the same time you alredy have gauges so perhaps the monitor isn't of high value to you functionally or aesthetically. One more thing I've been noticing lately is a high rate of failure among the Juice boxes. Not sure if it was a bad batch of them or if they're just cuting corners in manufacturing.

Tough call...

I'm having the same debate J/A versus TST. For those that have them is there a significant difference in time to install/uninstall? I've read the instructions PDF for both and I get the impression that the J/A might have a slight "edge" there.

 

[SRadke]

Install time will be very similar. Both require a lot of plugs to be swapped around.

The Edge DEFINATELY goes to Edge on the install and uninstall. The Cam Shaft Sensor is a PITA to get to. You will have to be under the truck to connect or disconnect the Cam Shaft and Crankshaft sensor. Of course I think it is worth it and I don't worry about removing unless broke or changing boxes. My dealer service writer does a every time I go in with a different stack .

I went with the TST. I like the J/A, but wanted something that I could run zero fuel pressure with. The J/A for the SO/HO motors use some pressure, so you can't really stack it with anything. The TST will let you play with pressure box stacks, or run no pressure if you like.



The TST is a bit of a pain, but it only took me about 5 minutes to get the cam and crank sensors installed.



Cool thing about the TST is that they have a bypass plug available now. No need to unplug the harness if you have a problem with the box, or want to upgrade to the twins program. Only $10 for the plug.

I'm running a stock (and will be) 48RE. So 0 preasure or max power is not an issue (over 100hp).



What about the fueling on these down low? I know TST has seperate controls for hp and tq. Doesn't the Juice also have a switch for intial fueling?

How is the power down low?



I know you can stack an EZ (ect) with the TST but that is several hundred more, and why do you have to? Is the power down low not there?

The new juice for the 555 adds some preasure, does that help the low end? Also why on the 555 and not the 600? Does the 600 intially have more preasure?



Enough questions to be answered? :-laf



Thanks

Well if your not tired of hearing this here we go again!





I LOVE MY HOT J/A! It's easy to install, easy to remove if needed, never know, and you can sell those old gauges and recoup some of your money.

Just so everyone knows, Mark at TST finally made a "dumby plug" to plug into the harness's so you can send out the PMCR for a flash and not need to remove the PITA cam sensor harness. Kinda like Quad did on his modules

 

[Tomeygun]

and ohh yeah, I vote TST... If your into that whole "high hp" fad

 

[ECappleman]

Stll would like to know which has the most low end power though.

 

[JCleary]

TST Twins flash, for sure.

 

[ECappleman]

TST Twins flash, for sure.

Not on a stock truck.

Pressure helps the low end! And yes the 600's do have more initial pressure. However, it is my opinion that Edge needs to get rid of the fuel pressure part on the '03-'04 version of the Juice to get rid of some real quirky stuff going on(PM me if you want and I can get into the details) - then it will be awesome like the later model Juice's on +04. 5 trucks. Also, if you can convince Edge to provide the Juice with 5 power levels without having to buy the Attitude monitor, which is a waste of money if you already have analog gauges, then all the better too.



If you want the best "low end" boxes IMO consider the VA C3. 1 or the TS MP8 ("old" Ramifier). Yes, the VA has low "peak" power ratings, but who cares if you want this power/torque in the lower rpm for towing anyway. The MP8 fuels like the VA down low, with infinite adjustability, but doesn't peter out on the top end like the VA does for EGT control.



If money is not an obstacle, I would consider some small injectors (Flux, 2-flows, DD1 or 2, etc) with an in-cab adjustable pressure box. Injectors are not "peaky" power like some boxes. Rather, they closely follow the factory power and torque curves and therefore are really smooth power adders.



IMO the more mechanical performance upgrades you can do, the less crap can go wrong. Picture messing around on the side of the road in crappy weather undoing all the box harnesses when you have problems to rule out these from the broke-down equation - don't ask me how I know this.



That being said - I do love my TST twins even though I normally run around town with it on 1x0 :-laf

Not on a stock truck.

Depends on how fast your truck will get other stuff. Any box with alot of low boost fueling can break a turbo input shaft...



But if you plan on upgrading quickly, just save the time and get the twins flash, Heck I run the TST/twins - EZ stack on stock turbo and to 42psi alot... Did it break? nope, are the bearings a bit weak, yep



anyway, just matters what your plans are and how soon

Yes the juice does have what they call "low boost fueling" It allows five levels of

adjustment for each level on the box. Of course you have to have the A2 or attitude monitor to be able to adjust these levels.

 

[ECappleman]

Don't plan on any upgrades for awhile (need some cash :{ )



Just trying to figure out which box gives the best low end for towing and the best overall for the buck, with semi-controled EGTs.

Is there such an animal?

 

[ECappleman]

Also could you use the TST twins program on a stock 48RE ?

 

[SRadke]

You *could* use the TST twins program on a totally stock truck, yes. I don't suggest it however because of how it fuels. You'll never be able to go higher than level 4 without damaging something and it isn't very smooth because it ramp fuel in too fast. You're better off to get the standard program and have twice as many setting with smoother power and still have more power than your stock components can handle. Then if someday you choose to go twins or a big single, TST will reprogram it for a minimal charge.

 

[ECappleman]

Maybe wait and see what the new capTURE box is like when it is released?

Should be in about a month.
