so i've decided i'd like to try the tnt but i heard that it doesn't work very well on the 03 04 trucks, and heard that a tnt file just for the early trucks was comming out. is this true? is it already out?any body know.

The TNT works on some 03/04s, not on mine, at least not consistent. The rumor is a new program is in the works....

With the current TNT programming I have noticed I cannot change timing or shift defuel options without reloading the whole sw#, it just won't take.

I had turned the shift limit off, I did not lose my shift indicator, I did it several times, shift indicator still illuminated. It wasn't until I change sw# that the effect took place, no shift indicator, then I could not get it back on with selecting adjust options menu. I had to load a new sw# to get my shift indicator back on.

I believe the timing function is behaving the same way, if I try and change the timing through the adjust options menu, truck timing sounds the same, the rattle does not increase or decrease until I load a new sw# or reload the existing sw#, then I get the increase in rattle.

This could be why it would run ok on sw#6, timing 3, rp1, tq2. Then I would select timing 2 and it would run the same, no apparent change. Then I would load sw#8, I believe then the timing would change to 2, and it would pop and buck like crazy, reload sw#6, same popping and bucking.

So if my theory is correct, I am going to reload TNT, adjust my options first with timing on 3, then load the sw# of choice, other 03/04 owners have had luck with TNT and timing 3. I guess we will see what happens.

thanks for your input. i am getting the popping in third gear when i use the quad pressure with the smarty so i took the quad off and am now wanting a stronger smarty file.i guess mabey i'll try it. can you go back to the regular revo after loading tnt?

You can go back and forth between regular Revo and TnT. If you are getting popping using the quad pressure... then chances are you are losing RP. Going to TnT won't fix that. Or, it could also be that with the quad pressure, you again have too much timing. Try this: Use a smarty tune using stock timing and add your quad into the mix. If it still pops, it is RP; if not, it is timing. Then use TNT with stock timing and compare... most of the folks having the popping issue on 03-04 never try the stock timing to fix the issue. What Marco is doing, in the simplest (not most accurate) explanation possible, is re-mapping the dynamic timing curve to pull timing out in upper rpm range to cure the popping. My guess is as long as you have enough cp3 to fuel the tune, you could use TNT, stock timing, and your quad together.

The tunes work fine in our experience. The timing and other options are not designed to work on the fly, you have to reload the software (even the same #)for the adjustments in the options menu to take.

Tell me, what hp level has the TNT showed to be on sw 1 ? This was the first program I tried when I got the TNT on, left everything default. Got the pop in 3rd gear. Tried about 10 combos on sw1 and 3, every single one popped, and none felt remotely close to the beta 4.4 on comparing sws. Now how could I possibly be draining the rail if the truck doesn't do it on the stronger program but on the weaker one? I got the popping in 3rd gear, 2nd gear felt sluggish til past 2000rpms then picked up, 6th gear i could floor it with no popping. I still believe there were other issues. The 03-04 needs to have its own tune IMO, to keep things straight.

it's been mentioned many times on here and the TNT does not work on every 03/04 and thats for sure. I can't run timing on any level on TNT without nasty popping and believe it or not, I can't even run timing 4(most) on Revo without the nasty popping. I gave up and went back to a beta tune. The fix has been coming for many many months.

Erik@LCD

Thats pretty odd. Was the MP-8 in the mix at all? Did you try it with the MP8 removed? 4.4 has stronger low end fueling but it generally does not dyno weaker than TNTR. Is your rail valve capped? What are you seeing on the RP gauge? Its odd that 6th doesnt pop since that is where the greatest load is.

[QUOTE=soulezoo;2543760] most of the folks having the popping issue on 03-04 never try the stock timing to fix the issue.

I have tried the stock timing with TNT, I believe now that I understand the mistake I have been making. I was not trying to "adjust on the fly", I was stopping my truck, turning it off and selecting the "adjust options" menu and trying to change timing with that alone. I wasn't aware you had to reload the sw also for the change to take place.

Since I had originally used the default settings, timing being 2, by adjusting timing in the options menu itself, I was not affecting any change. My truck does not like timing 2. A few times I had adjusted the timing to 3, and changed to sw#6, it ran great. I changed timing in the option menu alone to 3, it still ran great, then I would try sw8 and pop and bang like crazy, it was also at that time changing the timing to 3, I would go back to sw6, and pop and bang again.

Thank you both, when I noticed the shift defuel acting like it did, I believed I had figured it out, You both just confirmed. The Serial # on my S-04 is 98, I have had this since Bob came to Spokane for Diesel Thunder in 05. I have had numerous tunes in it, I believe it could be made easier to understand.

Quick question, does smarty adjust rail pressure?

rip 112

Not only was the MP-8 set on 0, it was unplugged underhood also. The rail is not capped. That is on my list for when I get ready to tackle the fuel system some more. The RP gauge don't work. Just havent' sent it back yet...


I just don't understand what the deal is.

i was running the quad race and it ran fine until i put the flux 2's in then i got the pop. rail pressure was solid at 26000,and is capped. so i took it off and bought a smarty and had no pop on any level.i sent the quad in and had the pressure tune put in to run with the smarty,at first it worked good now for some reason it pops as soon as i turn it on.so its out of the truck.i think something went wrong with it? so i was just going to run the smarty alone but want a stronger tune.

You have to realize that each and every truck is different, even if it has the same build date. One thing that may work on one truck may not work so well on another truck. With that being said my 03 305/555 runs extremely well with the Smarty TNT. I currently do not have the popping that everyone is experiencing with there 03-04 305/555 Trucks. My Settings are SW9, TM 3, TQ3. I do also run a pressure box on top of my Smarty when I am Drag Racing. I see 28,500 psi without it ever tapping off.

It can if you want it to... from levels 1 (stock) through 4.
