New everyday car 2022 IS300 AWD. Seems that Lexus has detuned the V6 to 260HP, though other models report 311HP. Has anyone tried the D3 Performance Tune to modifiy ECU to increase HP and Torque? What results?

There seems to be some discussion here as well: https://www.clublexus.com/forums/per...s350-tune.html

hey OP, did you end up buying the tune?

I just bought the d3 tuner for my 2022 IS300 and It was preloaded with 2 tunes, HP and torque. Just tried HP tune and immediately feels the difference. Very smooth acceleration and nice engine sound.
Used to drove IS250 and 330i, and was impressed by stock IS300 already. After tuning, this is unreal for me. It feels like a totally different car now.

I recently bought the d3 tuner for my 2018 IS300. Previously had a 2015 IS350 so my IS300 always felt down on power. The d3 tune changed all of that and then some! My 2018 is much faster now with very smooth acceleration. It truly feels like a different car now.

Anyone know if the d3 tune will work on a 2016 is300 AWD?

They have a version for the 2016 on their site.

Have any of you that purchased the D3 tune done any 0-60 timings? Just wondering what the power gains will look like on the road. I’ve seen the dyno numbers for the RC on d3s website. I got a 2020 IS 300 AWD. I was waiting for RR racing to come out with a tune but they still haven’t been able to crack it. Looking to see if the d3 tune is worth it and if there are actual power gains. I’ve seen some say there were next to no power gains and some with crazy improvements. Just looking to see what you guys have found, an if possible guys with 2017-2020 model IS 300 AWD.

No. Dealer indicated it "could" void warranty. Though I would like more hp etc...decided not to move forward.
