Sorry for not replying for a while. So I have this tune from D3. Need to do more tests to see if it's what they really say on the specs for the profile. Once I get some hard numbers then we'll see.

 

good to hear. Do you notice any performance upgrade so far?

 

From switching to stock and back (a week each) I've noticed some differences and idk, maybe a placebo effect but I feel like it pulls more and the engine just comes alive much easier.

But it hits 7k rpm on the Rev limiter and doesn't go higher, it bounces off which if tuned shouldn't. Either as a safety or it doesn't change much in performance. I will say too that there are 3 profiles to choose. Regular tuned, high octane tune and extreme throttle response (touch the pedal and it just flies).

I've driven with the regular profile for a long while and again seems like it does 'something' but can't be too sure. It should be really noticeable. I'm loving the extreme throttle response now and performance but again could be just in my head. I did the test when it was cooler, now I should do it again during the summer with summer tires and actually get a dyno done. Definitely will keep people updated!

 

This thread made me sign up for ClubLexus after surfing only (almost daily) for 8 years. I feel the exact same way. Got a 2018 300 AWD to immediately tune to a 350 (plus any additional gains) using D3 performance. I’ve been through all three tunes, using 93 Octane as they specify and I think the only difference I feel is a placebo affect. I thought the difference would be stark since we started with a de-tuned engine. Did you notice a difference with the enhanced throttle response? I was expecting it to fly when you blip the throttle… or at least be noticeable.

 

With the enhanced throttle it definitely does pull harder. My gf even loves it when I turn off traction control (Hold for 10 seconds) and just tap the gas. Using the 1st profile to the enhanced throttle you'll feel a bigger difference in less delays (obviously). But again I still feel like it could pull harder. Been to other cars that have similar setups with a tune and they fly. I understand I don't have turbo or a supercharger (yet, hopefully they'll make it soon, RR is apparently in the works) but still at least something. I love my car and with an intake, exhaust and the tune, I feel like it was much better than all stock for sure. The car sounds and feels so much fun to drive. I just need hard numbers to see what's really going on to feel better about it. I just want a supercharger damn it! Lol

Don't worry, I'm the guinea pig so I'll let people know what to go for and what to avoid in regards to mods since NO ONE ELSE has tried anything on the new gens or posted it.

 

Hey man, any news on dyno/dragy numbers? How’s the tune holding up?

 

There IS a major update!! So apparently there is an updated version of the tune, and man this thing is no joke. It really is a difference. I knew something was up on the previous tune and it wasnt what i thought people talked about. Once i got the update downloaded and installed, you can definitely feel the difference in pull and RPMs. I havent gotten around to dynoing (is that a word) it yet, mostly procrastination on my part so i cant really say 100% its worth it so i can use real numbers to tell the truth. Im going to schedule something hopefully within the next couple months and check it out, just need to find a place thats local and will give more updates.

 

This is awesome! Makes me so much more excited for mine to come in. Question, did you try fiddling around with the tool wizard and modifying rev limits/shift points etc? I know that was an option but haven’t found anyone who’s done so yet like I plan to. Butt dynos don’t lie! Probably gonna wait until i have full intake and exhaust setup to go get dynoed (i’d say thats a word why not) which will also be within the next couple months. Keep me posted on updates and I will too!

 

Yup! I completely forgot about that awesome feature! Yes, thats how i managed and created different profiles for different things. My daily/current one is the high rev limiter with enhanced throttle. Once you turn off traction, the thing just pulls you pretty good into the seat. You can work with however gets you the software and they can show you for a few minutes how it works and its real easy.

 

Thats awesome!! I’m gonna get a dragy and do pre tune/post tune runs with stock components then pretune/post tune with cai and catless exhaust (no headers for our gen sadly) do you have instagram? If so follow me i’ll be doing build upgrades along the way @****ty3is *****ty3is but s instead of $ club lexus likes to keep it pg haha, man it won’t even let me use money signs $HlTTY3is

 

Hey man, been a while and unfortunately i havent had the time to dyno or do any testing. I did find your insta. I barely use mine only for following builds or buying parts for the car lol.

Have you had any luck on your end?

Plus i heard from D3 that they are looking into getting a tune set for a supercharger kit for 18+ IS so im in the lookout for that.
