VF Tuner ECU/TCU Tuning for the GX550

Thank you for the response, and that’s great news!
And yes, our octane limitations up here are quite frustrating given that we produce so much oil up here, and have 3 refineries. I’d imagine it must have something to do with our relatively low ambient temperatures up here, but then again the overwhelming majority of the population lives below 500’ above sea level, so who knows.
Regular is 87, mid-grade is 88.5, and premium is 90 octane.
can I also request the AGM battery voltage like on the Tacomas ?
First impressions...I went right to the 93 Octane +TCU version.
Transmission is much smoother, both up and down shifting. Before, acceleration from a stop felt sluggish, now it really gets up and goes! During normal driving, you'd never "know" the engine is flashed, but wow, there's a shitload more torque and acceleration there when you want it. The engine seems happier, operates far more smoothly, and is just a lot more fun to drive. Recommend this VF Tuner product 100%.

Thanks fir this review.. I'm really wanting to do this ... Mines only a couple days old so little nervous about "tuning" and causing issues with my extended warranty.
Another plug for mileage increase with the tune!
I had a drilling jobs up in the high country of Arizona in Show Low and Flagstaff over the past couple weeks and my average MPG running up to about 7,000 feet and back twice was 15.72 mpg over 3 tanks of fuel. One one tank of nearly all highway I averaged 17.64 mpg. This is loaded with work gear, camping gear, and awning on the roof rack, cruising around 80-85 on the highways.

Yeah, I re-read the whole entire thread again and I gained some confidence on the map swaps.. If I were to have any issues with the drivetrain or major items i think i'd swap out the 91/87 for the stock just incase.. But you are right.. not a high probability of that happening or the likelihood they would know there is a tune there.
I guess most likely during dealer maintenance intervals and status checks, they would be interfacing through the OBDII port so might be a good idea to at least zip all the wires up so they won't notice.. I do plan on keeping the CAN Connect cable/module there so I can minimize popping panel off.. Thinking on pulling the trigger..
I have a trip to Florida so i'm thinking on driving it to there from Texas in stock form, logging the miles and fill-ups THEN implement the tune.. If not, I won't have a good feel on the butt-dyno how much i'm getting for the money.
So I need to by the CAN connect cable + the Tuner WiFlash package?

hey Folks, we are offering a limited pre-order on our new 3.4 big mouth intake manifolds.
Pricing:
If you do NOT have a tune kit: $1899
if you DO have a tune kit: $1299
Volumetric area increase of 30+ %, and increases lower area volume for more equal distribution to the front cylinders of the engine.
This is made on a 9 axis CNC and will be 100% Billet Aluminum. even at $1899 with a fully billet piece of this complexity is almost unheard of.
We are limiting this to 4 orders only, and you get a discounted price if you can send us some pictures of it installed.
We can even make a deal and pair it with a Magnuson upgraded water to air intercooler as well (which makes a huge difference).
This will come with an updated tune specifically for this and the increased flow.
Specs : 30% increased volumetric area / flow capability
Billet CNC T6061
OEM fitment (no cutting, deleting, etc of any component)
utilizes the areas for increased flow that the OEM uses for plastic stability
Designed in the USA
Black Anodized

What benefits could be attained by changing out the manifold and the intercooler?

1. Significant change in BATS (boost air temps)
2. No heat soaking like the stock unit
3. Much better heat control at high boost
4. More power. Power is reduced by temps, and temp management allows even more power
5. More power and flow distribution on the manifold

Once the GX is at least half way through my warranty period i'll do this hehe.. going to be hard to hide! Love it though. Tune first i guess

I believe these cars are too new for anyone to have experienced this, as last I recall new cars in California only get inspections after 5 years.
Older customers who have got inspects have not had any issues at all. Surprisingly the only place that people have told us they must flash back to stock is Denver. Even on CARB approved tunes, some folks have had hassles with Denvers policies.
Never heard of such from a CA customer.

no reliability concerns at all. We have brutally tested our Tundra for several thousands of miles on a "can we break it" tune to really test how far the engine can go.
+/- 3 hour install. Since you have to remove the intercooler to install the manifold doing both at the same time saves tons of time.
