Check my 3rd gear log (celica)
Finally did a pull but my app is using gs for maf .the highest I saw was 2700gs
D is rpm e is air intake temp f is maf and g is timing

TBH i actually prefer g/s.....it's more granular
I hate to kill the moment bro, but I think you need to log again and/or convert the units.... I don't even think Brad with his 8 million hp C63 has 2700g/s of airflow... It should be in the hundreds...
I normally like to have the following fields set up as I find them the most important:
Being **** fuel trims are nice to have, but only if I sniff a problem. Air temps I only really look at if timing looks off.
The reason why throttle opening is important is because sometimes I've found that even at WOT at the pedal in the car, the TBs might only be at 78% at 5000rpm (like my car for example) and that should be factored in if trying to benchmark.
Also, a tip - make pulls in manual mode to ensure that you get the very last drop of rpm to 6700. I can see your car short-shifted on line 674 in S mode probably. Annoying, i know. Sometimes, you might need to do several pulls of the same gear and rpm range just in case it didn't get recorded the first time.
(and if you round to just 1 decimal place, it wouldn't do any harm )
I'll fish out a P31 C63 later when I get home and try to draw some comparisons. I think....from memory that around 6000-6200rpm is around 270g/s @87% throttle. But...I think that car was at higher elevation. Oh yeah, is yours at sea level, or....?

Here is an updated run.i just wish the app had a faster refresh as I took it to 7k but it logged off throttle and only got to 6100 going wot.
some tuner needs to crack our tb to open 100% as you can see my tune is only opening 86% going wot in 3rd gear.
my gs is 357 at 6k and would probably read 370gs at 7500rpms
timing on this file is 25.5 a little aggessive but it' cold out
53 is intake air temp...as mentioned before these cars have amazing intake setups from the get go.ambient temp was 42 degrees

I'm half asleep reading this post, but I'm almost positive that those numbers aren't adding up....my guess is that it's not a clean log (sucks, i know - I find I need to do several redline pulls to get a good picture of what's going on). I'd have thought at around 6000rpm you should be in the high 200's... 357 even at 6700rpm would indicate a strong motor for the mods..
25.5 timing is good....i wouldn't say aggressive until you're in the 28s./29.
I'll have another look tomorrow when i'm more awake

from my cell
357gs is 47.23 lb/min at 6100 rpms doing some online calculators I'm at 85% volume efficiency at 6100 rpms

Perhaps take a few more logs to validate the readings....?
I'm looking at a 2013 C63 log (a fairly strong log/car - 470whp - dynojet - headers - USA car) and at 6600rpm it's ingesting just under 330g/s. At 6100 it's at 310g/s.
I guess right now, your throttle opening would help a lot, because it might be that it's opening a few more degree's at that lower rpm breakpoint than some of the logs that I've seen. I see other logs of cars in the high 200's (285-290g/s) at around 6000rpm, although altitude is probably a factor. I'd expect you to be at near enough full throttle opening at 6100rpm though...
I'd love to log some UK M156 cars with my HP Tuners scan tool as it's precise down to a T, whereas while the Torque App can be very useful for general knowledge and data, I find that it can be inconsistent at times and it leads me to question the data. Take most of the stuff I say here with a pinch of salt, because most of the logs that I see are from Bluetooth phone apps....actual data logging equipment logged data is hard to come by.
P.S. 86% is 1 degree away from full throttle

Your MAF readings (if correct) is really good.
My car would flow in the mid 270s on a good day. Although I am at 5700ft above sea level, if that makes a difference.

Is there anyway without opening up the manifold to find out what throttle bodies I have?
mind you this log is full bolt ons without cats.i would say I'm around 485whp right now.my last dyno was 443whp before doing headers.
the thing is my car was a renntech car when it was bought from a dealer in miami.the pictures they showed me had the renntech airbox installed.i had a dealer in md find me the car so it bounced from Florida to md then to Boston and at some point a dealership took the box.(spent 3 months fighting and almost got a lawyer involved) and my car had renntech badges and tune on it when I got it.
so I'm like 50% sure the previous owner had the tbs installed also as he also bought the 10k dollar renntech wheels that were on the car at one point.

I would assume the colder air and sea level makes a huge difference so you can' really compare endless we both ran together .

I think I have pushed the max I can get into this car without going to a super charger.my only bottle neck now is the stock mufflers and resonators.
I have hit 372gs/sec trying new things and I the next step is the renntech box and is not worth the squeeze.
If I run no resonators and new exhaust I might hit 380gs but it's not worth it.the car pulls hard and I can't wait to hit the track next season.
Here is my latest pull....10 min ago.

Here's a 3rd gear log from my car.
Temperature outside was 50 degrees
181m above sea level
AL = RPM
AQ = Timing
AS = Intake air temp
AW = MAF in g/s

Eurocharged dyno tune
2nd cat delete (H-pipe)
Resonator delete (Straight pipes)
Charcoal filters removed (If that even does anything)

Looking good Scratch, I like it! OE tune, right? Looks really good tbh.
MTV10....even better. Bang in line with what the V7 should flow. Some headers on top will see you touching 500 to the wheels
The sampling of the data is a bit misaligned, but I guess we have to accept that, being Bluetooth phone apps.
For the sake of general comparisons, I think we should all be looking at 6700rpm, as that's the stock rev limit and an even playing field.
