Alright they are teasing us with those stage 2 numbers!

Totally understand this.. but I find it odd they used 3rd gear which is not 1:1.

Mustang dynos usually measure lower because of the power absorber being eddy current vs pure inertia.

BTW a/f "stoic" on a dyno would be a really bad thing....

Octane is at the center of my curiousity as well.

Reason being, if the stock Toyota ecu is capable of adapting when on 91 octane and above... then what's to keep a tuner from just filling their dyno truck with 91, and claiming those gains as their own?

If Wikipedia is to be believed, the 1GR-FE is already doing 285 hp and 289 tq on 91. So the posted gains are only a little higher than that.

However, if their gains are on 87 octane, I am super duper interested. Because that'd put them over 300/300 on 91 octane, I'd have to believe.

How they achieve the gains is also of concern. They likely reduced the pig-rich AFRs in a lot of places... but I wonder if that might reduce the safety margin when towing (high load/temp situations).

All said and done, would really like to see some testers post real dyno runs. Vivid's posted dyno charts are weirdly simulated. Can't trust those.

While extra hp is always good, the truck already has a decent amount to be honest. What we all really want is that damn throttle lag tuned out!!!!!!!!!!!!!! Make it completely linear from tip in to mashed fully. Make it resemble a throttle cable's response and most of the griping on this forum will disappear.

If cost is not too bad I would be interested in this once warranty period is over.

I am unsure why this is an issue as Pedal Commander/Sprint Booster does this already. As far as I am aware we have vendors that offer 30 day trial period with 100% money back guarantee.

In my mind it's advantageous because it becomes one less "add on" to worry about and pay for. Also those devices don't really eliminate pedal lag, where as re-programming the ECU would. For those who don't want to re-flash ECU then ya PC/SB are decent options.

have you tried either PC or SB?

I guarantee you a tune will have disadvantages. The biggest one being that Toyota will not warranty your motor if it blows because of a tune. This is a fact of tuning and modifying engine characteristics outside of OEM parameters and they will void engine warranty.

Not yet, but I would like to.

Which is why I wrote this...

Besides, you could say the same for adding a black box. Toyota could void the warranty because you've changed the vehicle's OEM condition. A tune (if done properly) will ALWAYS be better than add on black boxes btw.

There is almost no reason why you should risk your motor with a tune if all you want is throttle control. You already know the cost of the tune - $500 without the handheld tuning device and $750 with the device. But risk of blowing your motor has cost too which cannot be easily factored.

PC/SB is ~$299. PC/SB already does throttle control and has almost zero risk to the motor if you follow directions. PC directions state that in order for you to avoid a CEL situation that you must have the ignition off for at least 5 minutes before disconnecting the throttle wire.

In the past some dealers would void warranty simply for having none OEM equipment installed on the vehicle, before any motor damage occurs. In stricter areas (like where I live) adding this same equipment could also land you in trouble with your insurer, so it's not necessarily a no risk mod.

Also you keep insinuating that a tune is bad for the engine and that it's risky business. Why? Nobody mentioned a high strung tune pushing the limits of the 4Runner engine. You get what you pay for, right. A bad tune would inevitably lead to big problems. A good tune would not. It would just free up some lost hp and drive-ability tuned-out by the manufacturer.

Lastly I didn't say I would get a tune for the throttle mapping alone, that would be silly. I would get a tune for all the added benefits it gives driving and enjoying a vehicle (hp, mileage, shifting logic, drive-ability...) and the throttle mapping would be an added bonus. In reality a properly tuned ECU would negate the need for a PC/SB and URD MAF Calibrator (plus what other add-ons may exist for our trucks) in one neat package for those so inclined. Just another option for the consumer which is never a bad thing.

I must've misunderstood you when you said -

"While extra hp is always good, the truck already has a decent amount to be honest. What we all really want is that damn throttle lag tuned out!!!!!!!!!!!!!! Make it completely linear from tip in to mashed fully. Make it resemble a throttle cable's response and most of the griping on this forum will disappear."

I am certainly interested in a tune and understand the risks involved but from your own statement you made throttle lag the most important part and we have devices for that already without added risks.

If at any point you reply we will end it at that. I don't wish to clutter this thread.

What I am interested in is other peoples feedback on this tune.

My Vivid Racing tune comes in Tuesday next week. I return to town on Wednesday and hope to get it flashed by Friday. They said they have about a 24hr turn around time max on the tune file after you email it over.

I will post a review after some miles. I may not get to it by next week as Im leaving for New Mexico on Sat for a week and it might be wise not to tune for that, and my feedback will be clouded as ill be running the rig fully weighed down. Stay "tuned' lol

Can't wait to hear your feedback.

Putting it on a dyno?

Am I the only one who has no idea what these people are talking about when they complain about the throttle? It drives like any other SUV out there. The only issue I see with the car performance is it's horrible aerodynamics and need for some more torque.
