The torque dip is about 20 percent and the kw drop is around 15. Not sure its small. Ask your service mgr if the problem has actually been fixed or just quietened. If he's honest he will tell you they cant fix it just make it quieter. Ask the "lack of customer service Dept" and its a "characteristic of the engine". The service bulletin was for a remap (detune?) of the ecu. If you dont tow much weight (our van is 3t) you may never notice it but I have attached a dyno report for our 22 model with the "latest software" that shows the AFR behaving like a 1970 govt bus and the torque and power falling off a cliff. Toyota wont comment as to the effect on the DPF but at $7266 to replace its not a happy prospect considering their argument will be "its the way you drive". Dont be mistaken. If you own a 300 series you have this issue and this is how it looks. Seems someone forgot to do any R&D OH what a reeming Toyota Scan_20231114 (3) (4).pdf Scan_20231114 (2) (1).pdf

Not resolved. Toyota now say it's a characteristic of the engine. Personally I don't think a $120k vehicle should cough, whistle and surge uphill while towing but Toyota think it's fine. Don't know how they're allowed to sell vehicles with known faults

Sorry 2200 rpm

Wonder if anyone else is having issues with sporadic wastegate operation around 220 rpm towing on incline. Toyota apparently working on reflash for computer fix but to my way of thinking unless it is every vehicle it's unlikely to be a reflash issue.

Have an issue with wastegate operating at 2200 rpm while towing. Toyota apparently working on a computer fix. Wondering if anyone else has had this issue
