Could be tuning, but could also be something else. Some history and background??

Was rebuilt about 344000 kms ago. Replaced the exhaust pressure sensor since the tune and the IMAP was changed within the year. CAC is perfect. 35-38pSI boost on average. EGT’s run normally between 800-900 degrees. While pulling a hill and rpm’s reach 1800 the turbo might hit 950. We are hauling logs, so the truck is grossing 63,500 kgs. And works pretty hard. As well, from the factory it was a 550 hp, 1850 torque. Had KW turn it up to a 600, 2050. Now it’s MM’d at the same 600/2050. Runs way cooler than stock. Pulls a little better than stock as well.
