well i found a darn near new motor for my truck since i blew mine up awhile back. its out of a 2002 and only has 75k miles on it. just wondering if my DRAG comp will work on this engine. not sure if there is a difference between 99 and 2002. going to use the 2002 computer and harness so just wondering if the comp is different for these years or not.

 

Yes, The software is different. 98.5-00 01-02

 

well if thats the case then i am just going to sell it and buy a TST comp. y is it that most say you cant run the TST on higher levels. whats the purpose of have a box that you cant run on high levels.

 

DANG! I just bought a Comp for my 99.
The TST, for whatever reason, makes the best dyno numbers on level 6, of 9. I think the higher numbers are just for higher RPM usage, but I can't say for sure.

Something to consider on your engine swap. You could keep using the 99 electronics. You just have to swap them over. The VP44 should be the same. I think you'll have to bring over your cam sensor because the 2002 engine does not have one. You might also find that the 99 electronics talk better to the Dodge PCM, although I do not know for sure if the 2002 electronics will have problems in that area.

hey chris, how many levels are on the TST? i no the comp has 5 with 5 sub settings like 5x5 and so forth, is the TST only say level 1-9 or is it like 9x9? all i hear is the TST is the ultimate box and its an fuel only box plus its the best stackin box so i might as well just sell my DRAG comp and go that route.

 

I have a TST PM3 Comp, and I just bought a Edge Drag Comp, if that tells you anything.
The TST has just 0-9, 0 being no input from the TST, but the boost fooler still works.

may i ask y you went to a DRAG comp instead of the TST? i have a DRAG comp on right now and loved the setup but i keep hearing the TST is more powerfull. should i get a TST for my new 02 motor or should i get what i have now, the DRAG comp?

 

I have a PM3 Comp now, stacked with an Edge EZ. The TST causes a mysterious shudder in the engine when you let off the accelerator, if you don't run it out to 2500-300 RPM when you get on it, at power levels of 4 or 5 (mine does it at 5, but others I have heard it happens at 4) and above (does this regardless of the EZ). A friend who had this setup, but got tired of the shudder, tried a Comp and actually made 3 more HP, but does not have a shudder, ever. The shudder can feel like the engine is coming off it's mount and is on the way out the hood. It's that bad sometimes. I don't know that is has ever caused any actual damage, but it is quite unnerving.
Those are the first 2 reasons.
The final 2 reasons are the finer adjustability for the lower RPMs (sub-levels), and the fact that on the lower main levels it actually DEfuels, which I like due to the sprinkler-head injectors I have in my 99. I'm trying to control the smoke when every-day driving.
I originally got the PM3 at the recommendation of the friend that has now switched to the Edge Comp. He learned and I am learning. He tests all kinds of boxes, and on a Dyno, so it isn't just seat-of-the-pants testimony.
I am not saying the PM3 is a bad box, as it has gotten me into the 12's, but I feel like the Edge Comp offers more to my situation, and I don't have to stack it.

so horsepower wise they are actually about the same. so basically a DRAG comp stacked with a smarty is just about the same as a TST/smarty stack. i know with my DRAG comp and my injectors, if i was to punch it and let off fast, my truck would die and i would have to crack the injector lines to get the truck started but i never experience the shudder you talk about. thats the one thing i really like about the comp is that it defuels so with big injectors, you can drive daily with the comp on say 1x1 with almost no smoke. very nice feture.

 

I don't know but my buddies 99 QC short bed, 5 speed 3.55s with a EZ/TST stack would smoke my cousions 01 QC long bed 4.10 5 speed with a drag comp.

Both trucks ran great (99 had 155k, 01 had 100k), they even swaped trucks and even with my buddy drivin the 01 his truck would still out run it.

Now I understand the weight difference and 4.10s but after 2nd gear the 99 would pull by about a good truck length.3rd gear in that 99 was the money gear it pulled long and very hard.

With all that said I drove both trucks and I didn't like the edge on any sub level below 3, didn't like the low in end but a great box.The EZ/TST is hard to beat but I've never drove a smarty/TST stack either.

 

The reason the 99 would smoke the 01 is because of the gears. My and one of my buddies both have the same trucks; same boxes, same injectors, 5 speeds. Only diff is that he has 4.10s and I have 3.54s. I can beat him so bad it ain't funny. Now pulling wise, he can pull a load better than me. But empty I can mop him. Plus, I get much better fuel economy than him. He did put some 35's on it, which made it run alot better. I just have 285's. But I can still beat him.

 

yeah i really think i am just going to sell my drag comp and get the TST. everyone says it shudders really bad but if it gets me a win in a street race, i can deal with the shudder lol. plus you dont have to drive with the TST on all the time or in high settings so i dont know y people says it shudders all the time, y dont they just turn it down a level or so.

next question, how many levels does the TST have? i know it has atleast 9 but then i hear people saying about horsepower levels as well as torque levels. is this right or am i missing something? i was told the TST does not have sub levels so how and the heck do you know if your on a certain horsepower level and certain torque level? sorry sounds stupid but i have no experience with this box.

 

TST pm3 has 9 levels with no sub levels for the 2nd gen vp44 trucks. I think you are hearing about the 3rd gen common rail trucks. They do more than just fuel, I think they do pressure 2. There are more settings, etc though. I don't have a CR truck so I don't know the ins and outs of it though.

 

ok here is one more ? for you . y do alot of people say you make more horsepower on lower levels than you do on upper levels. whats the point of buying a box that is only really usable on the lower levels? i was told you make more hp on level 6 than you would on 8 or 9?

 

Hey I'm running an 01 comp box on my truck, its an 02 truck. The wire harness is different but the program is similar. You should just try it. I heard that there is some program changes between the truck but what does that mean. Worse thing happen just send the box to edge and have them reprogram it for your truck. It not going to wreck anything so try it. I just use my drag box for dyno events.
