I bought this truck and got the delete done with the same guy that did my 3 09 year model trucks with Isx older version (no problems at all with those trucks ) , I really believe he didn’t do a good job on this 2012 Isx15 (cm2250) because the noises coming out of the turbo and the exhaust are always erratic and I always have a VGT actuator out of calibration check engine light on , I have replaced the turbo and the actuator 3 times and still the same but other than the weird noises and turbo perforomce the trucks was running just fine (but still believe something is not right with the way turbo sounds ) and the engine didn’t lasted more than 8 or 9 months after delete was done .However I have rebuilded the engine and took the truck back to this guy to make sure he gets the calibration right but it ended up worse now , he tried to reprogram it and what I’m getting now is black smoke and the turbo doesn’t seems to work at all . Engine is powerless now and tried take to another guy who told me that adding more HP will make the truck run strong again , ( I know that is completely a joke because the truck pulls but still blowing black smoke and turbo not working either ) .
I was hoping I can use some advancing here at this forum , it got the point where I don’t know where to take the truck anymore , so I bought me a Diagnostic computer , I got pretty good , I wanted to see if somebody can check and review my ECM calibration and make sure it sits as it should be to de-mandate the engine the right way !
It being a CM2250 (assuming you live in a country where that stuff is allowed),
Sad part is that you could have de-mandated that thing yourself for free... the right way ... if ya would have just asked around on here before wasting all your time and money on 'guys you trust' which is by the way.. a complete joke!.
