Peak hp at 7250 rpm
 
My car has been on a dyno twice and both times peak power was around 7250 rpm.

This is somrwhat confusing or maybe i havent seen enough other 370s dyno charts but others seem to make power up to 7500 at least.

Is the motordyne m370 causing this?

Car runs great this is just curiosity and confusion

Base models make peak power around 7k rpm. But if you see, it's nearly flatline from 6500 till 7500. You might have a couple mods that pushed your power up at higher rpm. The M370 will reduce top end power by a couple hp.

Nismos reach peak power at 7400rpm, most likely due to a better breathing exhaust

Normal. Check the rating from Nissan, they post the peak HP @ a certain RPM

As long as the power doesn't drop off considerably after 7250 I wouldn't be concerned at all.

Non-nismo makes 332@7,000RPM
Nismo makes 350@7,400RPM

Those are the factor specs

Mine made its peak hp at 7343 after the tune and 7323 before it was tuned. (with the cat back and CAI) So I would say you are about normal.

Indeed. I have new knowledge. Thanks

My graph also shows peak around 7100-7200

Check this out, my 7at shift from 1-2 at 7625 rpms fall to 5950.

1-2 gear shift at 7230 rpms fall to only 6300. My 1/4 trap was 1 mph faster.

Lol.... gonna stop watching replays

i still have the videos showing this i believe

is that AFR accurate? if so you are running dangerously lean

Im using AFR (measured) ftom torque and i believe so because prior tune was around 12.7 or so during WOT and with this tune it obviously a little higher.

I swear though if i have to get a retune im driving 900 miles to z1 to get it
