Doesn't seem like there is enough room to get any real increase.

Well, this isn't good news for me (300HP and less than 660ft/lbs). What do you know about the 2500 that limits to 700 ft/lbs?

I would rarely run at WOT or max torque, but am I wasting money if the Banks (or other) tuner limits HP and torque for my engine/tranny?

Your using peak numbers for comparison, this dyno graph explains it better.

You can add a lot of power without exceeding the limit.

We have the Allison 2500 and the manual lists those as the max input limits.

I'm not sure how it would add power if we are already sort of maxed out based on the tranny limits. If you running up a hill climb with WOT wouldn't that be using max available hp and torque?

FWIW I tried a Edge EZ on a '99 5.9 ISB (Not common rail) in a previous coach and it will NOT work.

I now have a TS Performance MP-8 on my 2005 Cat C-7 350. Love it.

Sorry for the delay in responding. Got busy yesterday.

If I understand correctly from Freightliner my engine (ISC) can only be computer tuned for a Grand (). If I wait till the warranty expires it is about $300. Can you address this at all? (I have the Allison 3000 MH).

Thanks for the information, because the boys at Banks were all ready to sell me a tuner.
Now I have to figure out some other way to spend money I've squirreled away from the admiral's vault

The reason it is a grand is it keeps your warranty in tack, and some times extends it.

Well worth the investment.

Sorry I don't have anything for the ISC.

I'll check into this option further at a later date. Low priority at the moment because we travel so few miles a year and the coach has performed satisfactory for me. The DEF system is what I am concerned about. The burn tank is $15K ! Don't want to damage it.

Thanks for all you have shared. I hope your not in CT at the moment. NE is a great place to be from, especially in the winter. I am a LONG way from MA. OR to be exact.

Happy trails.

Rick Y

Diesel tuner, had one for Ford F350, it really worked well, the duelly hauled it's rear end fast, downside towing it sucked down the fuel, 6 mpg down hill. Now I have diesel pusher, checked into having it re-rated, told the engine was max out. So I have no need in buying a turner. Yes, it worked well in my unloaded pickup.

There was something very wrong with that F-350 and or the tuner.

They always gain mileage with a good tuner typically in the mid to high teens.

Sorry you had a bad experience.
