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?

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.

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.

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.
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.

we will all know more once the hybrid turbo gets tested and tuned by TTI.

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.

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.

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.
