Engine/Transmission (1998.5 - 2002) tst pm3 stacked?

[hemijustin]

i have a pm3 and im looking into stacking it with something. posibley a EZ. or maybe a catcher. has anyone run one of these combos ? or is there a better set up. should i just get a Edge comp? hate to waste all the money i spent on tst. im going to take my truck down to cummins west and have them flast the ecu back to stock so that i can be rid of Dr. P... .

I've got my pm3 stacked with an ez and it runs great. Seems like it has a better low end now and I did shave a full second off my 1/4 mile time. I know some of that had to do with my driving, but the ez helped. I've had it on for about 8k miles with no problems and the pm3 never comes off 9 unless I'm towing. Get one, you won't be sorry.

doesnt come off nine!? isnt that hard on VP44? i usually run mine on five, but i agree it really needs an improvement on low end. i get hardly any smoke also hmm. whats dr. p? and why are you reflashing the ecm?

Dr. performance stage 2. I don’t know what they did. Some thing to the computer. (there is no box or chip on it) they put in injectors of some sort but they were only supposed to give better mileage. They also put a boost elbow on it. What ever it was the truck dynoed 250hp 520 ft lbs befor i put the tst on it. So I want my computer back to stock so i can know what I have.

How’s the smoke when u get on it?

Ps. The truck had the dr. p on it when I bout it

ahh you lost me there previously, i see! ok with the tstpm3 as you know the way it fuels about 2000 is imressive, but has no comparison, smoke wise to a comp or bully dog (3rd gen) and as i feel that is always a plus. the catcher is attractive, injectors are great but the ez/tst stack is more cost effective and easier for current issues that i believe are involved in owning a tst pm3. i agree, i would ditch the dp2

 

[hemijustin]

yea the only downside is that its going to cost me 250 bucks to take off Dr. p oh well ill be better off in the long run

thanks,

I have the EZ/TST PM3 Competition stack and it runs very well. The EZ makes up for most of the low end missing on the TST.

How much smoke do you get? What the difference in the regular and comp versions of the pm3?

 

[LOtero]

mkoth, what other mods do you have? and have you run your truck at the drags? what kind of times are you seeing??

It really will depend on how much you are going to do to your truck. Marco's reprogramming won't add much to the TST comp. Adding a timing box will help slightly up to 500 hp but over that I can't see any 1/4 mile time changes with the ez on or off.

 

[hemijustin]

does the ez add fuel at low boost? because my truck seems to lag alot in first and second but 4th has a pull thatel catch any 4x4 chevy gasser. no smoke at all. once i hit about 1900 rpm it spools up nice. is this common with the tst? it looks like thats what your saying. im ordering a htb2 in sometime early next week. then maybe an EZ or injectors. but i want to upgrade my lift pump first... . and im going to have to get a clutch soon im looking at a con fe or possably a dual disk iv herd there kinda harsh though. not sure ill think about that later. when i have no money and a smoked clutch

 

[BillGotthelf]

I don't believe the EZ or DD timing box adds much fuel it deals with timing advances at the lower rpm-below 2400rpm. The TST box uses the pump wire to add fuel. Above 2400 rpm I believe the timing boxes have advance the timing as far as they can go which is the same as stock. Whatever fuel they are adding comes from the connection thru the plug in harness not thru the injector pump wire. The vp44 is only capable of flowing so much fuel no matter what electronic signals go into it and the TST comp maxes it out anyway.

You run out of gear before you get enough spool, especially in first and second with how low they are and how quickly you go to the next gear. Come on dude, 4x4 chevy gasser? You need to be hangin' with Camaros!

Catcher

Put a Catcher with the TST and you will have all the bottom end you need . What year is your truck? PM me on a Catcher, Sam.

Justin,

Mine smokes pretty bad when I get on it, but it's all controlable with my right foot. The difference in the stock vs. comp version of the TST is that the comp version doesn't defuel untill somewhere over 3K rpms. I plan to have mine reprogrammed to a comp, but I want a turbo first.

Aaron

 

[LOtero]

i have all but bought a ez to stack on my tst3. what all is needed to stack the ez? double a i like your setup, but are you still running a stock turbo with those mods??

what kind of boost and egt numbers do you see? did the EZ help with take off or low boost Situations. I am about to order a htb2 but im worried I may have some low rpm spool up problems. Thanks again for your help,

Justin

Not much smoke with just the TST, but the EZ adds smoke untill the turbo cleans it up, which is about the time the TST kicks in.



The Comp box runs max fuel till redline, while the regular TST will start to defuel at the factory settings, which I belive is about 2400-2600 rpm.

mkoth, what other mods do you have? and have you run your truck at the drags? what kind of times are you seeing??

TST Comp, EZ, AFE stage 2, 5" into dual 4" PDP exhaust, southbend 3600lb 12 cb dual disk clutch, -8an fuel lines with wildcat fittings.



No 1/4 times or dyno numbers, yet. Truck needs a VP before anything else right now.
