The engine load threshold no mph signal was set to 100% from 40% torque limit was set to 2200lbs from 2000 customer torque limit gear ratio set ot 58 from 1 torque limit ramp up time set to 1 removed torque limit w/pto

Hey they finally made it better. I called the district S/M and in 2 Days they had a new file to put in the truck along with some parameters which the dealer had not checked. One being the torque setting the other was some response thing that was set at 40% and they set it at 100% then the new file and its much better still not what one whould expect but so much better. Thanks for your help all!!

I called Mack and they sent another file to put on the ECM and it also did nothing. So here we still sit. Dealer said they were going to contact the DSM and see what to do they are at a loss too.

Well my Mack dealer was left scratching his head. they had the truck for 3 days and did all the tests they know of and still cant make it have any power. they said they could tell it was down on power but dont know what to do about it. I guess its time to go to another brand I cant believe they can build a piece of crap like that and stay in business.

Is there a bulletin number or flash number that I can give my mack dealer for this flash He says Mack says my software is the latest and greatest but He didnt specifically ask about the throttle response flash. Thanks

The dealer said when they went on Macks website it said my truck has the latest flash on it. So Im sending it down next week to see whats wrong with it. Thanks for your help

I have a Mack 10 speed transmission. The gears are 4.33 and the tires are 11/22.5. My fatherin law has a vision with a 427 and says it really pulls and its also a 2006. With just a 118K miles on mine I cant imagine it has anything seriously wrong with it.

Yes I have a boost pressure guage and it will read 30 if you have it under load at 1700 rpm but the problem is it wont get to the 30 psi until then it just seems it needs the fuel earlier. Also it wont lug with near the power of my 400 2001 CH. For supposing to have another 60 horse it is truly a DOG...

I have a 2006 Mack granite with a 460 and it seems the turbo doesnt start to spool until its about 16 rpm then you have to shift and it goes back down to 1450 and it just hits the wall. I was cruising on the 4 lane and went up a decent hill with light load and it dropped from 65 to 58 with 460 hp????? no way something isnt right HELP????
