  1. I'M gonna get it in the shop this week i will keep you'all posted on the progress- again thanks guy's
  2. I don't want to forget ANYBODY it was a team effor THANK'S FJH and MACKPRO68 i would be lost without you'all
  3. That is the direction i was headed in, i got home from work early today and started removing the fuel line i got the feed from the tank to the filter off but since i got the info from rhasler i am taking it back to performance and let them change the data files to the correct ones and let them know a real mechanic diagnosed the problem, i wish i was close to his shop and i wouldn't have to fool with these people....so glad i found this site, who know's where i would be without all of you - thank's everybody
  4. Thank's a million man, i suspected it was something electronic why the mack shop did not know this is beyond me but i could tell that the mechanic's were not trouble shooters if the shop computer didn't spit out the problem it wasn't going to get fixed.I hope they know what to do with this info.By the way i have not changed the transmission it is a fuller 10 speed that is what came in the truck.I want to thank you again and everybody that took time to help me --THIS SITE ROCKS IT IS THE BEST.....

  6. Thanks men i do apprricate the info and you taking time to help me.I will keep you posted on the progress.I will try another lift pump
  7. after every thing we have done to the truck mechanicly I firmly belive it is in the electronics and since i have changed the ecm and then had the new turned up to dump more fuel something is telling the ecm not to dump enough fuel or it's one of the other ecm's I do not kknow what this other ecm's control by the way my cruise stopped working after this happened
  8. Doesn't sound stupid at all like you i've seen this to had one that had a hole in it,how it got there is anybody's guess When we were checking fuel system we disconected main feed and run it to 15 gal tank and set it on the back of the truck, same thing still
  9. The very first thing i did was to change air and fuel filters at first i thought it was fuel filters that's what it acted like. Looking back i wish i had put oversize injectors in it but the new ones performance put in was the same size that came out of it.But like i said it was running fine until this happened so i didn't consider bigger injectors i thought maybe one or two had gone bad the mechanic at performance mack said that was about all that was left to try. If the computer is not letting enough fuel to the injectors putting bigger ones in it wouldn't do any good The ecm that is inside the cab, what does it control
  10. The truck ran fine for a year so it had good power then lost it. It is not that i think it should have more it did have more for a year.The way it is now is actually dangerous, i'm afraid somebody will run into the back of it with log's sticking out and i don't even wan't to think about how bad that would be i'm starting to think it may be better and cheaper in the long run just to put another engine in it a cat or cummings definatly not a mack engine i'm done w/ mack they want and do control every aspect of a truck they do not own this i do not like. Performance mack would not even turn up the horse power and this truck is not under warranty I did buy it from (ryder) in houston. We don't have a company with a dyno around here houston maybe, but i'm 40 miles north of beaumont ANYBODY WANT TO BUY A MACK TRUCK..........
  11. I mean just what itn say's i was going down the road and it started losing speed untill it was down to 45 mph, on a hill it all but stops i don't mean the batteries man this is why i posted here,nobody around here can figure it out.I am a pretty good mechanic in my on right ,just not a computer genuis and that is what you have to be to work on a mack. I had one of the best mechanic's in southeast texas work on it after PERFORMANCE MACK TRIED FOR 4 WEEKS but he works at a volvo dealership and dosen't have computer acess but he could check a lot of things and his last guess was the ecm after he did all he could.He even hooked gauges to check fuel pressure boost pressure.pyro tenp fuel temp, air in fuel hooked up a lap top and had another mechanic drive it down the hiway while he checked all he could But PERFORMANCE MACK is a authorized dealer they said that they removed the parameters and short of a overhaul that was all they could do. this truck only has 430,ooo miles on it -- it was running good going down the hiway all at once it stared losing pulling power and that what happened i haven't been able to restore power since. Runs good empty but add even a lite load (20 tons) and it does 45 on flat ground 25 on hills not mountains. hills i never have to down shift this pete i just bought making same runs i made w/ mack..i no it's a stumper that's why i'm here but if you can't help i do thank you for tryingn and your time it had a 10 speed road ranger but it pulled fine for almost a year
  12. Updae i sent the new ecm that i bought to jballelectronics and paid $1200 dollars to have it "turned up" to give me more horse power another 1oo hp supposely.I put it on this morning, no difference Don't waste your money on these ecm horse power incress company's it does not work, not for me any way
  13. TWO DIFFERENT SHOPST CHECKED THE WASTE GATE,HOSES FOR LEAKS ECT.. THE TURBO WAS CHECKED THROUGHY .The boost pressue is about 33 psi it just under the 35 psi mark..I don't think it is going into derate mode Because i can unplug the boost pressure sensor and it will derate and then it loose's power even in lower gears Forgot to tell you tha i have no codes showing
  14. Performance mack/kenworth in BEAUMONT TEXAS
  15. No smoke,pyro temp is good,bost is 35 psi under load,fuel pressure is 80 psi Also forgot to add changed injectors and checked fuel lines
