It seems like the performance of my truck with the PM3 Comp does not change between level 6 and level 9. Now I wonder if this is because I have stock injectors, but DavidTD says he has not seen much difference between level 6 and 9 on these boxes on the dyno.<br>Has anyone with a PM3 Comp exeperienced the same thing? Has anyone tried the stacking of whichever box on 6 and 9 to see if the gains between 6 and 9 are more noticable, both stacked?<br><br>Thanks,<br>Chris

Level 9 keeps the fueling in place whereas the lower levels backs it off at 2700 rpm...I think. LOL<br>On the ETH I do not 'feel' much difference in those levels until over 2700 on Level 9...all the time, with my 6 inline... <br>Definate difference from 5-6.<br><br>But thats old hat for me now as I have the new truck en route ...in black in case I never told you. ;D

On levels 6 through 9 of the PM3 Competition version, you'll feel virtually no difference on an ETH equipped truck. It'll be a little more aggressive on bottom end fueling. With an ETC equipped truck, there is a great deal of difference between level 6 and 9, up to 40 HP. You likely won't see this on an intertial dyno though, as the TST box requires some load on the truck to allow the turbo to build plenty of boost. Without the boost, the PM3 simply won't fuel heavy enough.<br><br>Rod

with all this talk about the PM3 they seem like real junk. I think u have talked me into using an EZ Comp when I get to that point.

An Edge DRAG Comp won't make any extra power than a Comp will on an ETH equipped truck either. The ETH VP44 simply can't fuel hard enough to do much more than 120 ponies with a fueling box only.<br><br>Personally, I feel the TST PM3 Comp is the absolute best box we can get for the 2nd gen trucks. Its got a better bottom end power than the Edge product, and we've had better luck with reliability. Don't get me wrong, the Edge Comp is also a good box, but I don't think its at the same level as the PM3.<br><br>Rod

I'm setting my watch to see how fast this thread melts down.<br><br>

Ok what is the difference in ETH and ETC, its trannys right? But which one is which?<br>Heath

When I ran on the dyno we didn't see much difference, and when I ran at the track Friday night I did not see any difference. That's why I wonder if I need to have injectors because, possibly, my injectors are flowing all they can by level 6 and the higher levels don't matter because the injectors won't allow the fuel to pass.<br><br>All in all, I REALLY like the box though. It provides plenty of ;D<br><br>Chris

I believe if you read what tst says you lose some power with the auto. I have not gotten my remote yet for my tst 2 give me a few weeks and then i can tell you about it with a nice heavy load on the trailer

Wouldn't that power loss be across the board, not just above level 6? <br><br>Thanks,<br>Chris

Your stock injectors will be choking you down some, and if the dyno you were on was an inertial, you're just not going to see favorable results with the TST.<br><br>Rod
