The 2nd Gen IS350's are quick. I am definitely making more power out the hole, but that V6 would catch up. That's why we need that limitation issue fixed, i'll be happy knowing that i can beat them.
Yeah the 350 would catch you in the “big” end but you would have enough of a lead by the 1/8 mile that you would hold him off. I’d say your car is a 13.2@102 pass. Have you ever run it?
Yeah well you have a tune so they probably over wrote your normal and sport mode that’s what most tunes do. I was just wondering if what I’m experiencing is from 2017 and on or if the 2016 did it too.
TBH i experience the same thing but in normal mode it also happens lets say when you have the car in manual mode and you at certain rpm hold the gear for a few seconds and then floor it. wont hold the boost like it would happen if you put it into the same gear and floor it instantly.
Is like sometimes the ECU fights the tune. because i will do lets say a full throttle run and in first would boost only to 16 psi 2nd gear to like 17 and 3rd gear it would go all the way down or it would happen the other way around boosting more in lower gears and less in higher gears.

You're right. I can see high 13's, but I've never took it to the track, maybe once i'm satisfied with my results then i'll consider it.

OEM boost guage is actually very accurate. It reports exactly what the ECU sees.
I agree.
I ran a 9.2 with ****ty tires and spinning a little bit but last time i went i dont know why i ran a 10.2 and on my first run. now i have the stock wheels and firestone firehawks lets see how it does next time
Dude you really need to CHILL. You're own graph shows above 16PSI until 5500RPM then drops no lower than 15.5PSI. I never claimed the Turbo WILL HOLD 16PSI. I said, "We need to all understand at this point this turbo CANNOT hold any more than 16 PSI through out the entire RPM range."
The inlet on the turbo is only 40mm in size and gets shoved through a 36mm outlet on the turbo. the flow rate of this turbo is maxing out. The ECU is requesting more boost but the turbo CANNOT provide it. Look at your own boost graph. It's a peak then a gradual drop off.
@Sheddy.
Likely due to differences in DYNO used Mustang and Dynojet calculate things different.
Everyone needs to remember that horsepower is a fake number that is calculated off of torque. It is nothing more than an equation determined by the Torque curve.
Oh “At this point” I missed that. Yeah at this point tony can only make it boost so much due to tuning software limitations. I misinterpreted it, thought you where saying 16psi on the high end was the most the turbo can do, period. The turbo itself should be able to hold 18 peak 22-23 without ecu tuning limitations, which would rate to 290whp 350wtq. I just have a very strong opinion about OV and they’re terrible service so my bad if I came off rude. TTI bets out OV 100 to 1, even though I still think TTI has a little more hidden power to give up. There’s realistically no reason to look at OV expecially if they haven’t made any power advancements for the last 4-5 months. Ill continue to give anyone that advocates for OV the same advise, waste of money. They haven’t even come close to the R&d TTI has.
I don't think it's a software lock, but just a turbo that is designed for quick spool up and mid-rang power.
To be clear, so you think that our turbo is maxing out and can’t put out anymore power? Not because of a software lock

I’d have to agree to disagree. Yes our turbo has a 40mm opening, that air is thrown out the compressor into a 36mm exit. This is very typical for oem turbochargers and shouldn’t be considered a reason for not being able to push more power than similar oem chargers. Most oem turbos have a bigger opening on the compressor turbine and have a smaller compressor exit’ leading to the 2 1/4 or 57.15mm chargepipe. Our turbo can produce a lot more power...

Here’s an example of a focus ST k03 turbo, capable of 290whp/370wtq. Like most OEM turbochargers, the compressor intake turbine circumference is always bigger than the circumferences exit’ of the compressor. The focus St compressor turbine is 40mm/50.9mm. The 8ar-fts compressor turbine is 40mm/54.05. Consensus, we have a bigger compressor “turbo” than the focus ST. I’ve covered this in recent posts but I wouldn’t expect you to read the entire thread

Where do you get this idea that the turbo on our car can hold 18 PSI? Every other tuner is getting the same drop off as TTi and OV. I will reiterate that the turbo is not capable of more than currently getting. The ECU is requesting more boost but the turbo physically cannot deliver it. All the boost scramble boxes like BMS, TOM’S and the like show this as well. Those would get the extra boost if there WAS a software limitation.
The stock turbo on this car looks like a slightly modified GT2250 from Garrett in specs. Look it up on Garrett’s website if you don’t believe me.

No I think our turbo is maxing out on avalible boost pressure. More power may be there in fine tuning but it is not going to magically make more boost pressure that it is capable of making.
we will all know more once the hybrid turbo gets tested and tuned by TTI.

Again I agree to disagree. please don’t take anything personal but what makes you think it can only do hold 16psi? Do you know what a maxed out torque curve looks like? Our turbo can absolutely hold 18 psi with the support of a FULL tune. For that to be achievable we need a program that fully unlocks our ecu by disableing factory limitations. You can turn the turbo up and request a 24psi target pressure but it won’t hit it if you don’t have the fueling,vvti, cam, throttle nd torque maps to support it. The 328i n20 turbo, compression ratio, displacement, bore/stroke, internals are all identical and produces 300whp holding 18psi and 350 wtq peaking 23psi. I would encourage you to read the entire thread. We’ve done many comparisons in the past

to be honest this is all you really need to end this discussion. The K03 can peak 24 and hold 20 but I’m sure that’s due to a few years of fine tuning in order to unlock it. Not
We should all know that boost pressure is not the only factor for making power, we need those limitations fixed, IAT's down, A/F ratio etc. I want to see what Tony comes up with on this update.
Would also love to know the TRD TG20 Spec A details.

Let’s talk about the K03 “holding” 20PSI.
Here is a 18PSI tune.
Now direct you attention to the last 1000 RPM where it is below 18 PSI. Also note the boost pressure is lower than our car at 6000RPMs. There is more to making power than boost, bore, stroke and compression ratio. The K03 is running out of steam in this graph too.
