Installed my TS Performance MP-8 this morning. The roads are wet but in will spin 1st and 2nd. Seems more lively. Been about 12 miles on it. Later today I will turn the know all the way down to see if I really can feel a difference. It is cheap, $347.49.:rolleyes:

I can see the mpg's going up. About 19.5 now. Will try some interstate miles Tuesday. Seems livelier also. I think that it was worth it.

Thats good to hear.Let us know how it effects the regens.

Let us know how it works out.

Don't judge your MPG gains by the DIC. You need to hand calculate the mileage.

It still is a couple of mpg's better than it was.

Update. 81 miles on the interstate this morning - 24.8 miles per gallon on the DIC. Stopped at one toll booth. Set cruise at 70 in morning rush hour traffic. Had alot of people pass me. Lost alot of the mpg's shopping in the city for about three hours. I am impressed.

I guess the next real test is to check out the TS performance claim of "undetectable"...
Is the throttle response any better down low?
I'm interested in this tune, but still have some reservations...

Thanks again for your feed back. I appreciate it.

It is not a tune. They raise the fuel pressure to 26,000 psi.

Thanks for the correction. I meant "Tune" in relative terms.

It is not a tune. They raise the fuel pressure to 26,000 psi.

Stock pressure is over 29,000. Mine showed 29,980 at WOT.

Again, check your claims by hand, because I'm betting your DIC is way off because of the change in programming!

The TS is not a programmer. It only raises the fuel rail pressure. I am averaging a little over 20 mpg's (hand calculated) which is over 3 Mpg's than I was getting. Which is also about 7 more mpg's then the 2011 6.0 which I previously had. You can feel a performance difference. No easy access to a dyno where I live to prove this. Anyway's I am happy with it even if some of you are not.

Does the TS box piggyback the stock wiring harness? If it is changing fuel pressure, it is modifying the tune and thus is a type of programmer.

It may not be a making cal. changes but it is making changes.

The TS MP8 is a universal performance module that holds eight brand specific programs. It contains all diesel brand applications on one chip board.

The MP8 holds eight programs and when the appropriate harness is connected it will access the programs for the application and it will marry the harness to the MP8.

In other words its a PROGRAMMER my friend!

I don't know what one you looked up. The one I have is vehicle and year specific.

Either way, (what ever it is...) I think for $380.00 if it improves fuel economy,HP/TQ, and is truly "undetectable" it would be worth the money in my book...

Have you noticed your regens increase or decrease with this unit?

whmayhew did the ts box help throttle response? What I am looking for is more power early in pedal not just 3/4 to full throttle like H&S tune. To me lmls feel lazy till 3/4 throttle.

Keeping power where the factory designed it is the best way to save a transmission. If we tuned on the Allison we would bring power in much sooner on the LML and give a better pedal response. We feel that most guys would rather lose a little pedal response in trade for a longer lasting transmission.

We will have more aggressive tunes available at some point, for those that like the really sensitive pedal feel.

Thanks H&S. I will look forward to that tune. all in all your first tunes are very good.

That would include me...:) Sooner or later its bound to break though.


Thanks for the hard work HS! You guys are great!

I also just changed from the 6.6.6 update to the 6.6.7....WOW.... what a change....
I love it!!!

I will try it tomorrow.

Please, PLEASE!

I made my 06 last for a long time with stronger tuning, so I'm not worried about hard parts. Just give me my pedal back...!

I hated the throttle response at first, but now with the hot tuning and turbo back exhaust i love being able to take off at a light with light to medium throttle and no smoke.

Question: How does the MP-8 make 100hp+ without raising rail pressure beyond factory specs?
Answer: The Mp-8 is the only box on the market of it’s kind. Both the map sensor and the fuel pressure sensor are fully programmable. By reprogramming the map sensor signal you achieve several things… 1) since the map senor thinks it is at different boost level it will add injection timing accordingly. 2) This is the primary reason we don’t have to raise rail pressure beyond factory specs and risk damaging engines.

Its a form of a programmer just in a sly/ im gonna fool you type of way ;)

Seems like a good deal but I still see no way that they can make it undetectable. Don't these new trucks monitor the torque levels through the transmission and if they see anything higher than normal they throw a flag that will make you lose your warranty? I thought I read that somewhere and if that's the case there is no way to run this and still keep your warranty.

You are correct, If the truck is making more power it is going to get recorded somewhere in the system, so aside from strapping a rocket to the bed while in neutral, WE ARE SCREWED!

I had one on my LBZ and id gave me a false MPG reading on the DIC. So just do the math and see if it's correct

Any long-term updates on how the MP-8 is working or impacting regens?

Bump.............. Anybody bright there trucks into the shop for any warranty work sfter installing one?

do they mean undectable as they dont reprogram the trucks computer but they intercept it & change it before it gets to the engine like banks 6 gun does?? so your factory tune has never been pulled out & changed.

Undetectable meaning where gm can't find that u used an aftermarket device for power increase. And the mp8 is a pressure box It is far from a tune
But never say never I don't know wether or not has brought their truck in that has one, so who knows!

Check out Thoroughbred Diesel. They bought an LML and are testing out various products on their Dyno. I was surprised by the dyno numbers for the MP-8.
