How much of a difference does the comp version of the TST pm3 really make. Anyone know? I have the edge drag comp which I really like more than the TST but was thinking about upgrading the tst to competition. Then see which I prefer and get rid of one of them. What your thoughts

 

I have no clue -- but maybe some cummins guys can jump in here for ya...

either way, here's a free bump..

 

Just not a lot of us usin the TSTto be able to offer much info. It's always been reported to be a good solid box but the price is a little steep for what your gettin for most folks.

 

You wont gain anything over the Drag Comp. Hp is about the same give or take a few. Differences I've seen is were they come in hard at and how long they fuel. The TST fuels longer and a bit harder up on top.

 

The biggie with the TST that it is fueling only, no timing. SO, perfect to stack with, say a Smarty or Superchips, something that does both fueling and timing.

 

I had a TST hot comp and it fueled real hard. But now I have moved on to bigger and better things like the REDLINE box. The TST made my turbo bark if I got out of the throttle to fast. I didnt like that

 

I ran both the standard and the comp upgraded TST.

The Comp version was NOT street friendly above level 5. Nasty shudder.

Level 5 on the Comp version is comparable to level 9 of the standard version. It fueled much harder off the bottom and was much stronger through the midrange.

well not sure if it's worth the upgrade. I really like my drag comp better but thought maybe comparing apples to apples (tst with upgrade) would change my mind. I thought about putting my mad ecm back in and running the pm3 comp version. then sell my smarty and drag comp. Now I'm stuck again

 

One thing is for sure. Different components work diferently on various trucks. I talked to a guy today that hated the Smarty so much his head was ready to explode.

The next breath, he couldn't stop priasing it in a buddies truck.

So, everyone is different and there's lots of opinions on the subject. I built a work around fix for the Smarty issues I was having. But later felt that by adding even more components, I was increasing my chances of failure.

For the street, you will not find a better stack than a drag comp with a smarty, IMO. I have tried them all. I have a redline for pulling and I take the smarty off and use my drag comp as an EZ. I have a JVD torque enhancer, I've run 4 TST's. 2 PM3's and 2 Competition Versions. Just to give you an idea.
