just read the post about the J35 recall/class action bought my truck in april and looks like i may have slipped through the crack and did not get a letter.
my truck is still stock. I was wondering what effect on performance/mileage the recall has.

thanks

 

No difference in performance. Big difference in DPF operation (better).

 

I had it done last summer and was pleased with the results. Mileage increased somewhat and the truck ran a little better all around. Of all the recalls and reflashes I've had done I believe the J35 recall made the biggest difference.

 

i had it done and i did not notice any milage increase in fact i lost about 2 mph but the regen works better
