Will the downpipes be louder in the cabin?

 

[LitterMuncher]

Will there be tunes to accommodate just the DP and intakes/inlets (less important lol). Inlet/intake, DP, and 93/flex tune sounds like a great sweet spot for us causal folks

 

[munkeeboi]

Accompanying tunes for just a DP and inlet/intakes would be what makes me buy those parts. Don’t need new turbos….. yet

 

[VF Tuner]

If you have our tune kit you'll get updated tunes for these parts for free when the parts release.


Note, the downpipes will be high flow EPA legal CATTED ONLY. (no catless)

Curious, were you able to ever figure out exactly what they adjusted in the "shifting" TSB software update that was released now that you got your hands on it?

@VF Tuner any updates on updated tunes that have the transmission updates baked in?

Appreciate all you guys do.

 

[VF Tuner]

@VF Tuner awesome! Will they automatically be emailed out? Is there anything special I need to do to prepare?

Can you also please summarize what's changed in these updated tunes?

Yay!!! (For the record i saw the picture and knew WITHOUT cheating lol ). I bet this platform loves … I’m assuming it’ll be like a 30-40 mix instead of straight 85?

@VF Tuner Any word on the release today?

I am still here at my office working, once I have it ready I will release + details

 

[munkeeboi]

Are you able to provide an update on when this might be released or what the hold up is?

 

[VF Tuner]

Small hold up but nearly done,
as there are actually 2 new calibrations newer than the TSB released by lexus, already installed on some GX550s.
We want to confirm that these newer ones are OK on olders (just waiting for feedback from one person on that) then everyone gets the latest release, even newer than that TSB.


Changes to the tune include:
(premium fuel version)

• Updated load and Boost Control
