ok, i cant even hardly turn it past level 2 seems like everybody else is havin better luck, i dunno if my pump is weak or what but anything 3 and above and it just runs dry pops and cuts out, would the arsonII kit keep up with the tst? but im really just wondering if everything is right bcuz its like i will get a dead pedal sometimes then all of a sudden it'll just kick in and i even pulled up to a stop sign last night and it died on me...

What year is your truck TST does not worky on 06.5 and above.

MegaCabRam

yea thats what i thought at first but i looked and it was built 10/05...

Well TST is a really aggressive unit with only a Arson II kit probably is draining the rail, somebody will chime in here with more experience with the TST.

When you describe the "popping" that is a sure sign of rail draining. You don't say what version of TST you have, but you should have a RP guage on there (mine does) and you can watch to see if you are draining the rail. If so, it is time to mod the cp3 and get a better flowing lift pump.

But then you mention it died on you at a stop... I have to wonder if you have something else going on with fuel supply that is not normal or maybe a sensor problem. Have you thrown any codes?

MegaCabRam

yeah its thrown some codes but think the only fuel related one was somethin about high pressure common rail somethin i dont remember for sure, as fars as the lift pump i should be fine i would think? with the 150 FASS? and yeah the rail is for sure draining it drops down toi like 9 10 11k... but im still thinkin there may be another issue

soulezoo

The 150 FASS is fine... 9-11k at WOT is no bueno... the Arson II will help.

MegaCabRam

this may be a stupid question but does anybody run just the tst wide open? or will a single cp3 even support it? tst claims 190hp on a basically stock truck but i just done see how...

Not many do or could run with a TST turned all the way up. I can run 7/4 on my mods with either of the twins programs and some pressure. But anything else is just too much. I am sure some can run higher, but need a lot of additional supporting mods. Basically stock trucks I would think would be limited to around 5/2 standard program before they started draining rail or getting very HOT.

With just the TST I can run any of the settings...and it is a pig....Add the smarty and the most I could do was 2/1 and that was insane...

I ran the Tst alone and was not overly impressed.(dont think I have the mods to back it up)I was running Smarty revo with the TST recently and could not go over 3te/2pwer without having it break up when I mashed it.
I saw a post on here the other day aboutguys with 03/04 trucks being able to run smarty rail pressure at 3 for daily driving. I tried rail 3 and now I can run TST up to like3/4 and when i mash it, truck pulls like crazy.EGTS limit my increasing it anymore than that. In short,I was definitly draining the rail. I would post what my rail pressures are, But I dont have my rail pressure gauge yet
My tst has all the latest programs but my serial number is too low to be able to us the rail pressure settings.
I got way more bang for the buck with the smarty!!

I have the same problem and was wondering if the tst has a boost fooler built in because if not, i think the engine defuels at like 26psi. Am i correct or just mislead.

RamWheelsBy4

The TST does boost fooling, it also has max boost settings to defuel at.

I ran the TST alone for a good while and loved it, still do!!
Ive never had the TQ settings above 3 and always ran the Standard Program.
It is a very agressive unit and with a stock CP3 it will drain the rail in a hurry!
Im gonna be doing the Arson II kit, cause with the Smarty and the TST the poor stocker is getting a work out!
Id say get the arson kit.

i'm running the tst and have the same problem on 7/5, going to twin cp3
s to fix this because i really don't think the arson 2 can keep up with it. might be worht a try for 300 though, because twin turbos are in the future for me upgrading now, and saving the 300 for that.
