Which Paccar MX 13 do I have

Really cant tell a whole lot of difference with torque bumped from 1650 to 1850. It already did well at stock except for on a decent hill it falls flat on its face. I had a bulldog on it at 550. Black smoke but still dead on the bigger hills. On average hills it does fine.

 

Well i dont wanna replace the clutch. The rears might handle that much if i drive eggshell style but i dont know how well a 1650 would really handle 2050 and id still like to see a million miles. I got a few egt lights with the bullydog but havent had any with my tune. Dont think id trust bullydog that much thats why mine will only be used to read or clear codes.

 

Oh and also if u call bullydog they will tell you on the torque side you aren’t necessarily getting the 10,15 and 20% that the settings say.and they set it so mild as to not tear anything up that it doesn’t feel like a power house.
