Funny as I have a YotaWerx tune for my 2UZ-FE and a VF Tuner sitting here at my desk for my 2UZ-FE . I'm counteracting my previous posts, but if it takes the reliability down from 500,000 miles to 400,000 miles that is fine as my GX will rust out before that.It's a shame they de-tune the motor, there is a reason it is more reliable... I bet if they unleash the hp the Toyota TTV-6 reliability would come way down.
I have the 2019 TTV6 that is in the Raptor and 450hp and 510 lb-ft. I'm extremely concerned about this motor lasting very long but it will never be high mileage and damn it's fun to drive.
Even the LX is 409 hp and 479 lb-ft. It's kind of hard to compare the two as Ford designed theirs to get a lot more out of it while Toyota is taking the safe boring route they know so well.
If the 3.5TT is like Toyota's other motors it will be choked by a crazy-restrictive exhaust system that can be fixed without tuning it. Hopefully the 3.5TTV6 will actually be tunable, compared to my UZ 's ECU which took aftermarket tuners 15 years to finally crack.
