I couldn't get any input on this stack earlier, so I've convinced myself it should be a good stack. I decided to do it myself. I'm going to stack a Juice and the BDDL. This is the way I'm seeing this stack and why I think it should work. They have little to no fueling. That eliminates the fuel rail problem. They both probably have pretty fair duration. What I'm hanging my hat on re: duration is that the VA C3.2 and the TST are all or heavy in duration and I doubt the combo would surpass their duration. Then we're to timing. They are both moderate in timing. Even combined, that shouldn't present a problem. That's why I think this will work. How well,....I'll know this weekend as I'm doing it Saturday.

Here's the kicker which may drive me into the Nut class of members. Right now I'm stacked with the Juice and EZ. I'm thinking with very moderate fueling from the Juice and BDDL, that a little fueling might be in order by leaving the EZ in the mix.

So, ...what do you guys think about this combo.????

 

You might want to contact whitesport600 I think is his screen name.. I believe he's the only one I've heard of that is stacking 3 boxes on a 3rd gen. Not sure which 3 though!

 

I've read his posts and he's running a TST which is a lot more radical. Tks.

 

I would spend my extra cash on some tranny mods and a turbo upgrade so that you can use all of what you already have first. You are wasting a ton of power already to tranny slippeage and excessive EGT...and driving a ticking time bomb.

 

If possible, you may want to try to get each company to tell you exactly how much timing advance they are doing. From what I have heard lately, there may be a reason why TST stopped at advancing timing at 12 degrees. If that is the case and you can find out why, then you would want to ensure your stack does not exceed it as well. Just a thought.

 

Tranny mods done. Stage V. Turbo,..negotiating w/a couple different suppliers for the best deal now. Don't intend to waste anything, much less power. EGTs are not through the roof w/ Juice and EZ stacked. 1090 is the highest I've seen. I attribute the hood, intake, and exhaust to cooler than normal EGTs. Boost is at 36 now wot so I'll just limit boost and EGTs to do my driving-by-gauges until the twins are on. I'm getting some good advice on PMs from several and I will probably forgo the EZ in this stack. Right now I expect the Juice/DL to be doable.

 

Tks, I will check.

 

Sorry...did no know without the updated sig...my bad.

 

I do have a hard time believing that low of an EGT. What gauge and what location is your probe? Did both your Attitude and you X-Monitor give you this reading? Where are each probes? You are 100-150 cooler than a stock truck with a EZ/Juice stack? Hmmm.....

 

Pre is at #4 and Post is at #3. I have switched the pickups and they are virtually identical in their readings. I had had an '04 prior to the '04.5 so day one I switched the exhaust, intake and the hood. I never had experienced the EGTs that I see on the forum. The only difference I see from other rigs is the hood. To me it makes sense that hot abient air can escape and also when running then you have more cool air underhood. My EGTs did drop just a shade over a 100 when I upgraded the tranny.

 

You must just really take it easy...

 

Most importantly, after your post I went back and reread mine. I had a typo. 1190 is the
correct number. Me bad. What you seem to forget, ..check my sig., NO CAT,...no restrictive intake,..no restrictive exhaust. I suppose that buys me something in cooling or I and most of the guys on the forum spent poorly?

 

No...did not say that you spent poorly. Just compared your situation to the averages...

I do realize you are at a low elevation but...

Most trucks (4.5 and 03-04) can hit up to 1300 stock. Most intake and exhaust mods net no more than 150 degrees reduction. If you do the math 1150 is where you are sitting before fueling mods.

If you are able to make 150 or slightley more hp over stock with only a 40 degree EGT rise...you have found the magic combo. I was only trying to get you to think about other possibilities to explain your somewhat low EGT readings. If you are confident that both your gauges and probes are reading right...then maybe you are not really making that much power. Something else could be happening. Have you had your truck on a dino? I can hit 1200 or slightly more at about +150 hp with my much larger turbo. I can also hit 1400 at +200 hp with 45+ psi boost.

Load, elevation, speed, spool, and truck differences all make a difference. I do think it is important to compare to the average to have a reality check now and then. I doubt a SRT hood could cool underhood temps by more than 50 degrees on a cold day. That woun't have that much effect of EGT's IMHO.

Good luck with your truck.

 

Did you have a chance to test them out yet. I was wanting to do this stack to but i figured that since they both do the same thing that it would be pointless, but from how you put it it makes since to me. Let me know how it gos.

 

Brad,

Yes I did the stack this weekend and also put on the ATS Commander for full lock up. Frankly I'm struggling a bit with this commander to understand exactly how it's working. Probably have to play with it a few days to get on to how it's working and what it can do for me.

On the stack. I'll do a bit of a rewind b-4 I start. As you know probably, I had the EZ and Juice stacked. I felt very good results from that. I could run both wot without fear of egt or boost problems. I did have a code for intake sensor high (113) ever since I put on the EZ. It would come and go as far as the engine service light though,..weird.

I think I made a tactical mistake in that when I put on the BDDL I didn't erase the code first and then downloaded the tow program (lowest setting) and then plugged back in the Juice/EZ combo. I have the Juice set on (3-drive). The EZ is on the lowest setting for fueling (25hp). I picked up another code from when I put on the DL and it was (602-ECM communication error). Probably (I hope) from the previous code that was in there from the EZ. I'll have to repeat this whole process later this week to see if I just have a sequencing problem.

On Power,...on low end this three stage stack has more power than just the Juice and EZ,...I think. I say that because in everyday driving habits it seems to scoot a little better, but that is without reaching down and hammering it. The roads are screwed up today so won't be doing that. I did run it through lockup in OD as I wanted to see how the Commander did relative to the slippage percentage my Attitude shows and it was 0% slip. I'd say that was exactly what I was looking for. Pleased with that part.

Also in cruising to work I think I was running about 100* hotter on egts than with the EZ/Juice alone. Not that that was a problem overall as when I did the OD lockup thing which took me to just over 80mph wot, then it still wasn't in the danger zone on egts. More to come later this week or next weekend, .....whenever I get time to mess with this more.
