tst ts stack

[Jason Shue]

I have a tst pm3 and i stacked it with a ts mvp. When i hook the tst in the map sensor first, the ts dont add any timing and the tst wont boost more than 20 psi. If i reverse it ,they both work but still not boosting more than 20 psi. I'm running an edge ez right now and I'm boosting 42 psi. So what im asking is if anyone has any ideas for me

The TS box plugs into the ecm data plug which provides the timing and the tst box should plug into the map first.

I asked last time you asked this....What are you getting your boost readings from? Mechanical gauges? or the Display on the TST?

And how have you determined that no timing is being added?
tst ts problem

The tst is plugged in first and I am getting the boost from tst gauge . I can feel the difference when the timing box works and when it doesn't

anymore ideas guys

Lemme get this straight... You are getting 20 psi either way you stack it?

Also, when you say 42 psi with an edge EZ, is that by itself or stacked with the TST???

Stock turbo I assume?

Yes either way I stack it, it won't boost over 20 psi .Sorry yes it is stacked with the tst and I'm still running the stock turbo for now.

Then it sounds like something is funny with the MVPs Boost fooler maybe. I'm guessing you have a J hook if you hit 42 psi.

I would definately put the TST on the MAP sensor in the block first, no matter what you stack with it. Especially since you are using its display to read Boost (which is gathered from the MAP sensor)., You don't wanna "boost fool" the Gauge, know what I mean?

I never ran the MVP or the TST with stock injectors, but I bet BOTH are capable of boosting over 20psi ALONE.....

Examine all connections, Maybe wanna check the voltage on the MAP sensor just for peace of mind, and maybe wanna talk to Mark at TST about the readings you are getting from the TSTs display, and see if he can shed some light on it there...

Ok I will try that, thanks for your time.

I was deff able to hit 30 psi with the mvp and stock injectors with a load on the trailer that is. I could get 27 or so empty. now with the 100 hp injectors 30 psi is no problem. Sounds like there is somethin wrong with ur tst. maybe you should get a mechanical boost gauge an see what its sayin thier pretty cheap from glowshift.
I hate to here about problems with this stack. I'm planin on gettin a tst here pretty quick since i finally blew my clutch an got a good one last week.

[Jason Shue]

Its not the tst. I'm running an edge ez with it right now and I boost 42psi stock turbo with an j-hook and stock injectors. It's when I stack it with the ts it don't boost over 20 psi

what can u get with just the ts boost wise?
