Odd moment with the turbo (2017 453) (aftermarket powerpack)

The turbo on our 453 had an odd moment . Left home and the car was fine , stopped for fuel ( 91 octane ) and proceeded on the drive , came to a mountain and felt no turbo action . Had to downshift to 2nd to make it over the mountain , car was just a 3 cylinder non-turbo motor . Stopped at the base of the mountain and opened up the motor access , I found proper oil level and checked for any loose connections or anything out of place , found nothing . Started up the car and the turbo was doing it’s job again . Put in a 230 mile day without one hiccup . Question is has this happened to anyone else , question 2 was this in relation to the blowoff valve being in an “open “ condition and bypassing any turbo boost to the cylinders ? Question 3 Is this valve electrically controlled ?

Truly weird! So far after almost 4 years and 30k miles I have never experienced that. Surprised it had such little power, wonder if it was something else?

Our 453 has 18,000 miles on it . Normallly with the LORINSER exhaust , I can hear the turbo pushing extra pressure into the cylinders because the air really pours out the exhaust , that noise stopped and the lack of turbo boost was very evident . . I’m going to send a note to SMART USA to see if they have a direction I can go in their Tech Dept .

Yeah.... nearly 4 years and over 70,000 miles, nothing like that has happened to me yet, knock on wood. Hope you can find an answer somewhere.

Update : vehicle experienced a hesitation ,AND NOW finally threw a Code P061B: Internal Control Module Torque Calculation Performance. I detached my LORINSER powerpack and put on the bypass plug , cleared the code, the car runs fine now .. I’ve got a nice drive happening today without the powerpack , so I’ll see what happens . I’ve now sent an email to LORINSER to see if there is a program issue happening and IF I can sent it to them to check it out .

I'm semi-mountain and when I read that in your post I wanted to say depending on your altitude it was indeed the altitude change but then when I read your other post it was better understood from the after market crap you installed for the psychological gain.

I remember some years back I bought a very expensive set of coil and spark plug wires for my my Jeep supposedly to increase both fuel mileage and horsepower. They were so pretty in blue. And I was late 30's and still falling for the b.s.

No way in hell I'm discounting the German engineering in the squirrel. (in fact I wish it wasn't so much engineering)

Happy Motoring
